{{Excerpt|Climate change in Canada}}

Scientists across the world have already started to notice massive reductions in Canada's Arctic sea ice cover, particularly during the summertime. The shrinking of this ice results in the disruption of the ocean circulation, and changes in climate and weather around the world.{{cite web |url=http://www.climaterealityproject.org/ |title=Home |website=climaterealityproject.org}}{{Cite web |date=2021-09-08 |title=Anti-logging protest becomes Canada's biggest ever act of civil disobedience |url=https://www.theguardian.com/environment/2021/sep/08/canada-logging-protest-vancouver-island |access-date=2022-06-17 |website=the Guardian |language=en}} The 2019 Canada's Changing Climate Report, written by scientists from institutions around the globe, states that the impacts of climate change on Atlantic Canada will be very diverse. One impact is that the sea ice will become thinner and will also form for much shorter periods of the year. And with less sea ice than the region usually gets now, wave seasons will become more intense. Atlantic Canada will see a relative rise in sea levels everywhere - a rise which is estimated to be 75 to 100-cm by the year 2100. Scientists also predict that even if emissions decrease, a 20-cm rise is expected to take place during the course of the next 20 to 30 years.https://globalnews-ca.cdn.ampproject.org/v/s/globalnews.ca/news/5918981/climate-change-impact-across-canada/ {{Dead link|date=February 2022}} NASA studies have also found that a major ocean current in the Arctic has become faster and more turbulent due to the rapid ice melt, disrupting the delicate balance of the Arctic environment with an influx of freshwater.{{Cite web |title=Arctic Ice Melt Is Changing Ocean Currents |url=https://climate.nasa.gov/news/2950/arctic-ice-melt-is-changing-ocean-currents |access-date=2023-11-09 |website=Climate Change: Vital Signs of the Planet |language=en}} As the ocean warms and subtropical waters move north, the ocean will become warmer and saltier, and since warmer water holds less oxygen than cooler water, marine ecosystems can suffer and become less sustainable because of this lower oxygen level.{{Cite web|url=https://globalnews.ca/news/4657721/canada-fish-stock-decline-ottawa-report/|title=Canada's fish stocks plummeting — Ottawa needs a 'wake up call' to save it: Report - National | Globalnews.ca}}

In the journal, Science, which was published in March 2019, it explains that warmer waters could actually increase fish stocks in certain regions, like the halibut found off the coast of Newfoundland and Greenland but other species such as the Atlantic Cod and albacore tuna might not be able to cope with the conditions so well.

Wildfires are a major concern in Canada, with an average of over 7,000 wildfires occurring each year in Canada.{{Cite web |date=2023-08-22 |title=The Impact of Canadian Wildfires on Indigenous Rights |url=https://www.aclrc.com/blog/2023/8/22/the-impact-of-canadian-wildfires-on-indigenous-rights |access-date=2023-11-09 |website=Alberta Civil Liberties Research Centre |language=en-CA}} Since 1990, these fires across Canada have consumed approximately an average of 2.5 million hectares a year.{{Cite web |last=Canada |first=Natural Resources |date=2013-06-27 |title=forest-fires |url=https://natural-resources.canada.ca/our-natural-resources/forests/wildland-fires-insects-disturbances/forest-fires/13143 |access-date=2023-11-09 |website=natural-resources.canada.ca}} Wildfires are a recurrent natural disaster in Canada, escalating due to climate change and other human-induced factors. The situation has worsened over the years, with 2023 marking a particularly devastating wildfire season. The wildfires led to massive evacuations, with tens of thousands of people displaced from their homes. In British Columbia, about 35,000 individuals were under evacuation orders, and over 30,000 were on evacuation alert due to the intensifying fires.{{Cite news |last1=Helgren |first1=Chris |last2=Williams |first2=Nia |date=2023-08-21 |title=British Columbia wildfires intensify, doubling evacuations to over 35,000 |language=en |work=Reuters |url=https://www.reuters.com/world/americas/british-columbia-residents-high-alert-wildfires-force-state-emergency-2023-08-19/ |access-date=2023-11-09}} The wildfires also caused substantial property and infrastructure damage, destroying nearly 200 homes and structures in Kelowna, BC. The Canadian federal government, along with provincial authorities, initiated several measures to combat the fires and mitigate their impacts. This included deploying the military to affected regions, imposing travel restrictions, and soliciting international assistance.

The environmental issue of pipelines in Canada is a complex and multi-faceted concern, encompassing potential impacts on both natural ecosystems and human communities. Public opinion in Canada reflects a significant opposition towards government financial involvement in oil pipelines. Many Canadians opposed a multibillion-dollar writedown on the Trans Mountain oil pipeline by the federal government.{{Cite news |last=Williams |first=Nia |date=2023-10-24 |title=Poll shows 68% of Canadians oppose government writedown on Trans Mountain pipeline |language=en |work=Reuters |url=https://www.reuters.com/business/energy/poll-shows-68-canadians-oppose-government-writedown-trans-mountain-pipeline-2023-10-24/ |access-date=2023-11-09}} Additionally, Canadian governments have provided over CAD 23 billion to oil and gas pipelines in the last few years. This financial support was aimed at boosting the economy, but critics often argue it undermines Canada's green recovery efforts by potentially increasing carbon emissions.{{Cite web |title=Pipelines or Progress: Government support for oil and gas pipelines in Canada |url=https://www.iisd.org/publications/oil-gas-pipelines-green-recovery-canada |access-date=2023-11-09 |website=International Institute for Sustainable Development |language=en}} Economically, the new pipeline still serves as a strong case, helping open up newer markets for Canadian producers.{{Cite news |date=October 30, 2023 |title=Despite opposition and environmental violations, major B.C. pipeline project nearly complete |work=CBC |url=https://www.cbc.ca/news/canada/british-columbia/coastal-gaslink-fully-installed-1.7013274#:~:text=Until%20the%20pipeline%20and%20terminal,S |access-date=November 8, 2023}}

The Canadian Energy Regulator controls about 10% (73,000 km) of the pipelines in Canada, their Pipeline Safety Act, as a regulatory response, aims to mitigate several risks by enhancing pipeline operating safety and environmental protection measures. From a technical perspective, corrosion, construction defects, and cracking are generally the most commonly identified leading causes of pipeline leaks in Canada, emphasizing the need for robust maintenance and safety protocols.{{Cite news |last=Bakx |first=Kyle |date=June 27, 2016 |title=Pipelines and why they fail in Canada |work=CBC |url=https://www.cbc.ca/news/business/cepa-2016-safety-report-1.3654640#:~:text=Corrosion%20was%20the%20leading%20cause,main%20causes%20of%20pipeline |access-date=November 8, 2023}} Additionally, there are measures in place for preventing and responding to marine oil spills, including using satellite technology for detection and surveillance and advancing science to improve cleanup technologies.{{Cite web |last=Canada |first=Natural Resources |date=2020-10-05 |title=Taking action on pipeline and marine safety |url=https://www.canada.ca/en/campaign/trans-mountain/protecting-the-environment/taking-action.html |access-date=2023-11-09 |website=www.canada.ca}}

Species biodiversity and wildlife population numbers have been declining in Canada for decades. According to the most recent Living Planet Report Canada, species that are deemed at-risk of extinction have experienced an average population decline of 59% compared to 1970.{{Cite web |title=Species At Risk in Canada |url=https://wwf.ca/wildlife/ |access-date=2023-11-07 |website=WWF.CA |language=en-US}} Today, there are more than 600 plant and animal species throughout Canada that are listed on the Federal Species at Risk Act. This federal act utilizes a variety of measures to protect wildlife species that have been deemed endangered species or are at risk of becoming endangered.{{Cite web |last=Canada |first=Environment and Climate Change |date=2008-10-02 |title=About the Species at Risk Act |url=https://www.canada.ca/en/environment-climate-change/services/environmental-enforcement/acts-regulations/about-species-at-risk-act.html |access-date=2023-11-07 |website=www.canada.ca}} These measures are designed to encourage engagement and cooperation between individual citizens, local governments, and Aboriginal peoples.

There are hundreds of different species that are at risk throughout Canada, but a few of them are particularly noteworthy. The Southern Resident Killer Whale, commonly referred to as the Orca Whale, is an apex predator in coastal regions off the West Coast of Canada and the United States.{{Cite web |title=Southern Resident Killer Whales: Facts, Info & More |url=https://wwf.ca/species/southern-resident-killer-whales/ |access-date=2023-11-07 |website=WWF.CA |language=en-US}} These whales play a vital role in maintaining the resiliency and health of the ecosystems that they are a part of. Despite their importance, this species continues to face an increasing number of threats. Some of the most pressing threats are the result of habitat disturbance from human activity. The underwater noise that marine vessels produce interferes with the Orcas echolocation abilities, impacting their ability to locate food. Shipping activities also impact Orca whales in other ways including oil spills, ship strikes, and pollution.{{Cite news |last=Uguen-Csenge |first=Eva |date=December 3, 2020 |title=Ship strikes 'significant' cause of death for southern resident killer whales, UBC study finds |work=CBC |url=https://www.cbc.ca/news/canada/british-columbia/ship-strikes-significant-cause-of-death-for-southern-resident-killer-whales-ubc-study-finds-1.5826030?__vfz=medium%3Dsharebar |access-date=November 6, 2023}}{{Cite news |last=Kassam |first=Ashifa |date=2016-11-16 |title=Big oil v orcas: Canadians fight pipeline that threatens killer whales on the brink |language=en-GB |work=The Guardian |url=https://www.theguardian.com/world/2016/nov/16/canada-oil-pipeline-expansion-killer-whales-kinder-morgan |access-date=2023-11-07 |issn=0261-3077}} As a result of these threats, the current population of this species is estimated to be 71 in total. Their preservation is very important to marine health in the regions that they inhabit.

Another important endangered species to highlight is the polar bear. Two-thirds of the world's polar bears live on Canadian portions of the Arctic.{{Cite web |title=Polar Bears: Species Facts, Info & More |url=https://wwf.ca/species/polar-bears/ |access-date=2023-11-07 |website=WWF.CA |language=en-US}} Polar Bears are another apex predator that serve as an important indicator for the health of the ecosystems that they are a part of. The greatest threat to this species is the loss of their primary habitat- sea ice. Sea ice is where Polar Bears raise their cubs, and it is also the habitat for their primary food source, ringed seals. As climate change causes sea ice to melt, Polar Bears population numbers have fallen dramatically, making this species a direct indicator for the effects of climate change on the region. Right now, there are estimated to be around 16,000 Polar Bears throughout Canada.{{Cite web |title=Canada's Polar Bear Subpopulations {{!}} Polar Bears in Canada |url=https://www.polarbearscanada.ca/en/polar-bears-canada/canadas-polar-bear-subpopulations |access-date=2023-11-07 |website=www.polarbearscanada.ca}}

The Rainforest Action Network and indigenous groups have campaigned to protect the boreal forest of Canada from logging and mining. In July 2008 the Ontario government announced plans to protect some of the area from all industrial activity.{{Cite news|url=https://www.reuters.com/article/us-climate-canada-boreal/politicians-persuaded-to-save-canada-boreal-forest-idUSTRE4AI5IZ20081119|title=Politicians persuaded to save Canada boreal forest|last=Zabarenko|first=Deborah|date=2008-11-09|work=Reuters|access-date=2018-11-11|archive-url=https://web.archive.org/web/20181111062206/https://www.reuters.com/article/us-climate-canada-boreal/politicians-persuaded-to-save-canada-boreal-forest-idUSTRE4AI5IZ20081119|archive-date=2018-11-11|url-status=live|language=en-US}}{{Cite news|url=https://www.ran.org/the-understory/huge_news_for_ontario_s_boreal_forest_and_its_peoples/|title=Huge News for Ontario's Boreal Forest and its peoples. - The Understory - Rainforest Action Network|work=Rainforest Action Network|access-date=2018-11-11|archive-url=https://web.archive.org/web/20181111062201/https://www.ran.org/the-understory/huge_news_for_ontario_s_boreal_forest_and_its_peoples/|archive-date=2018-11-11|url-status=live|language=en-US}}

In 2021, the logging industry accounted for around 20 megatonnes—more than that of electricity production or emissions from Canada's Tar Sands.{{Cite web |date=2022-10-18 |title=Logging Is One of Canada's Greatest Climate Liabilities |url=https://www.nrdc.org/bio/jennifer-skene/logging-one-canadas-greatest-climate-liabilities |access-date=2023-11-09 |website=www.nrdc.org |language=en}} When it comes to the logging industry, the Canadian Government has failed to report accurate greenhouse gas emissions (GHG), absolving the logging industry from taking accountability for its contribution to GHG.{{Cite web |last=Baxter |first=Joan |date=2023-05-04 |title=Industrial logging is one of Canada's largest sources of greenhouse gas emissions: report |url=http://www.halifaxexaminer.ca/environment/climate/industrial-logging-is-one-of-canadas-largest-sources-of-greenhouse-gas-emissions-report/ |access-date=2023-11-09 |website=Halifax Examiner |language=en-CA}} Every year, the logging industry cuts down around half a million hectares of forest in Canada. It is responsible for over 10% of the country's total greenhouse gas emissions. The Canadian logging industry says its practices are sustainable and better than other countries. Critics say the current clearcutting and replanting methods contribute to significant forest loss and biodiversity decline, along with releasing carbon into the atmosphere.

The industry minimizes its role in environmental issues by deflecting responsibility on  “naturally occurring phenomena” when it comes to fires and forest loss.{{Cite web |date=2020-07-02 |title=The Canadian Logging Industry's Spin Cycle |url=https://www.nrdc.org/bio/jennifer-skene/canadian-logging-industrys-spin-cycle |access-date=2023-11-09 |website=www.nrdc.org |language=en}} Spreading misinformation has influenced logging policies in Canada, prioritizing short-term profits over environmental protection. This has led to the neglect of necessary safeguards, such as boreal caribou habitat protections and environmental erosion regulations. Ignoring its adverse effects on forests, communities, and the climate has enabled the Canadian government and logging companies to continue to widen the gap in creating a climate safe sector of logging.

According to the Alberta Energy Regulator (AER), approximately 170,000 wells have been abandoned in Alberta, Canada. These “orphaned” wells pose threats  for the surrounding communities and environment.{{Cite web |date=2020-07-02 |title=How are wells abandoned? |url=https://www.aer.ca/regulating-development/project-closure/suspension-and-abandonment/how-are-wells-abandoned |access-date=2023-11-07 |website=Alberta Energy Regulator |language=en}} Inactive wells pose a significant risk the longer they remain unplugged. When the hazardous materials from these wells are not properly managed, it can lead to the leaking of countless chemical toxins. Methane is a colorless, odorless gas that has tremendously more heat trapping abilities than CO2, and because of its makeup, methane can go undetected for years. The Wilderness Society also states that this leads to countless negative health impacts including, but not limited to, cancer, premature birth, and asthma.{{Cite web |title=What in the world is an orphaned oil well? {{!}} The Wilderness Society |url=https://www.wilderness.org/articles/blog/what-world-orphaned-oil-well |access-date=2023-11-07 |website=www.wilderness.org |language=en}} On top of that, the other undetectable toxins being released from orphaned wells gradually poison wldlife habitats, along with air and water.{{Cite journal |last1=Williams |first1=James P. |last2=Regehr |first2=Amara |last3=Kang |first3=Mary |date=2021-01-05 |title=Methane Emissions from Abandoned Oil and Gas Wells in Canada and the United States |url=https://pubs.acs.org/doi/10.1021/acs.est.0c04265 |journal=Environmental Science & Technology |language=en |volume=55 |issue=1 |pages=563–570 |doi=10.1021/acs.est.0c04265 |pmid=33322902 |issn=0013-936X}}

Typically companies must follow Alberta's Environmental Protection and Enhancement Act (EPEA) requirements for these abandoned sites. The process of reclaiming these sites requires specific criteria starting with a comprehensive site assessment determining the extent of contamination and the potential environmental risks. From there, these sites must create a reclamation plan outlining strategies for returning the abandoned site to a useful and safe condition. Based on the scale of the project, there must be approvals to ensure the reclamation work complies with relevant laws and standards.{{Cite web |title=Reclamation |url=https://www.orphanwell.ca/land-owners/reclamation/ |access-date=2023-11-07 |website=Orphan Well Association |language=en-US}}

The EPEA has a specific set of requirements for the cleanup of contaminated sites, which often requires ongoing monitoring and reporting to ensure that the reclamation plans are being met. These projects are tedious and can take years or decades to complete. As of 2020, Canada's Office of the Parliamentary Budget Officer (PBO) estimated these orphan well-clean up projects at costing around $361 million. By 2025, the clean-up process is estimated to reach around $1.1billion.{{Cite report |url=https://www.pbo-dpb.ca/en/publications/RP-2122-026-S--estimated-cost-cleaning-canada-orphan-oil-gas-wells--cout-estimatif-nettoyage-puits-petrole-gaz-orphelins-canada |title=Estimated Cost of Cleaning Canada's Orphan Oil and Gas Wells |last1=Forsyth |first1=Jamie |last2=Nahornick |first2=Nora |date=2022-01-25 |publisher=Office of the Parliamentary Budget Officer |language=en}}

Canada, like other countries with extensive mining operations, has significant environmental issues, including:

• Environmental impact of the Athabasca oil sands
• Cleanup of the Colomac Mine
• Acid mine drainage from the Northland Pyrite Mine
• Mary River Mine environmental concerns

In the year 2022 Canada announced a ban on producing and importing single use plastic from December 2022. The sale of those items will be banned from December 2023 and the export from 2025. The prime minister of Canada Justin Trudeau pledged to ban single use plastic in 2019. As for now in Canada "Up to 15 billion plastic checkout bags are used each year and approximately 16 million straws are used every day" {{cite news |last1=Newburger |first1=Emma |title=Canada is banning single-use plastics, including grocery bags and straws |url=https://www.cnbc.com/2022/06/21/canada-is-banning-single-use-plastics-by-the-end-of-the-year-.html |access-date=4 July 2022 |agency=CNBC |date=21 June 2022}}

Tar sands can be described as areas on land containing an unconventional mixture of sand, clay, water, and a petroleum based residue called bitumen, that is useful to produce crude oil.{{Cite web |title=What Are Tar Sands? {{!}} Union of Concerned Scientists |url=https://www.ucsusa.org/resources/what-are-tar-sands |access-date=2023-11-09 |website=www.ucsusa.org |language=en}} In the NDRC article it mentions that Canada is currently one of the largest depositors of crude oil in the world. The development of tar sands requires extensive infrastructure, such as roads and pipelines. Canada's oil and gas sector, primarily driven by tar sands, contributes 26% of the country's greenhouse gas emissions. Tar sands production has surged by 456% between 1990 and 2018, resulting in a carbon footprint larger than that of New Zealand and Kenya combined.{{Cite web |title=Everything you need to know about the tar sands and how they impact you |url=https://www.greenpeace.org/canada/en/story/3138/everything-you-need-to-know-about-the-tar-sands-and-how-they-impact-you/ |access-date=2023-11-09 |website=Greenpeace Canada |language=en-CA}} This expansion has led to the clearance or degradation of millions of acres of the Boreal Forests, endangering vital habitats for wildlife. The Boreal Forests serve as a massive carbon sink, however with these areas rapidly being destroyed there are even more concerns around air pollution and water contamination. Additionally, these extraction sites violate Indigenous rights as tar sands encroach on traditional lands, causing environmental contamination and health issues.

Refining of tar sands produces air pollutants, including sulfur dioxide and nitrogen oxides, which can have adverse effects on air quality and human health. This process produces three times more carbon emissions compared to the production of conventional crude.  According to another NDRC article, mining operations require flattening the forests in order to access the tar sands.{{Cite web |date=2015-12-31 |title=The Dirty Fight Over Canadian Tar Sands Oil |url=https://www.nrdc.org/stories/dirty-fight-over-canadian-tar-sands-oil |access-date=2023-11-09 |website=www.nrdc.org |language=en}} Extraction requires a substantial amount of water, which also contaminates local water sources and disrupts aquatic ecosystems. Leftover waste from tar sands processing, known as tailings, is stored in large ponds. These ponds pose a risk of leakage, which can contaminate nearby water sources and harm aquatic life.{{Cite web |date=2015-08-13 |title=10 Threats from the Canadian Tar Sands Industry |url=https://www.nrdc.org/stories/10-threats-canadian-tar-sands-industry |access-date=2023-11-09 |website=www.nrdc.org |language=en}} While around 150 Nations have signed a Treaty against Tar Sands Expansion, Canadian governments continue to support these projects, posing a threat to Indigenous lands and the environment.

Also taking a look at oil sands, methane projections from Canada's oil sands tailings using scientific deep learning reveal significant underestimation.{{cite arXiv |eprint=2411.06741 |last1=Saha |first1=Esha |last2=Wang |first2=Oscar |last3=Chakraborty |first3=Amit K. |author4=Pablo Venegas Garcia |last5=Milne |first5=Russell |last6=Wang |first6=Hao |title=Methane projections from Canada's oil sands tailings using scientific deep learning reveal significant underestimation |date=2024 |class=stat.AP }}

Alberta's economy, notably its substantial fossil fuel industry, poses significant environmental challenges, making it a crucial topic for discussing environmental issues in Canada. The extraction of non-conventional oil from the oil sands is particularly impactful, contributing to greenhouse gas emissions, water and air pollution, and land disturbance.{{Cite web |title=Climate change in Alberta {{!}} Alberta.ca |url=https://www.alberta.ca/climate-change-alberta |access-date=2023-11-08 |website=www.alberta.ca |language=en}} Despite this, Alberta is striving to mitigate environmental impacts by diversifying its economic sectors.{{Cite web |title=Diversified electricity generation : powering Alberta's future ESG performance - Open Government |url=https://open.alberta.ca/publications/esg-diversified-electricity-generation |access-date=2023-11-08 |website=open.alberta.ca}} The province's efforts to transition towards a more sustainable economic model, balancing economic growth with environmental stewardship, encapsulate broader environmental endeavors within Canada, portraying a microcosm of the challenges and actions toward sustainability.

According to the 2021 Canadian Census, over 1.8 million people self-identified as Indigenous.{{Cite web |date=March 22, 2023 |title=2021 Census of Canada |url=https://open.alberta.ca/dataset/487a7294-06ac-481e-80b7-5566692a6b11/resource/257af6d4-902c-4761-8fee-3971a4480678/download/tbf-2021-census-of-canada-indigenous-people.pdf |access-date=November 8, 2023 |website=Government of Alberta}}  Despite this demographic accounting for only 5.0% of the total population, there has been a pattern where most of the toxic, polluting industries and corporations are located directly adjacent to indigenous communities.{{Cite news |last=Drost |first=Philip |date=November 3, 2021 |title=Lack of control over land leaves Indigenous communities exposed to pollution, says activist |work=CBC |url=https://www.cbc.ca/radio/thecurrent/the-current-for-nov-3-2021-1.6235180/lack-of-control-over-land-leaves-indigenous-communities-exposed-to-pollution-says-activist-1.6218178}} This has placed a disproportionately high environmental burden on these communities, exposing indigenous peoples to the health risks that are associated with these polluting facilities more so than other Canadian citizens. For example, there is a region colloquially referred to as ‘Chemical Valley’ which has the largest concentration of chemical plants and refineries in the entire country – and this region is directly bordering the Aamjiwnaang First Nation, an indigenous community in Sarnia, Ontario. Members of this community believe that the air, water, and soil pollution from these chemical facilities has contributed to higher rates of asthma and cancer amongst its residents. In 2019, the United Nations Special Rapporteur on human rights and hazardous substances visited this region, and concluded that the Aamjiwnaang community, as well as other indigenous communities throughout Canada, are in fact disproportionately affected by toxic waste compared to other demographic groups.{{Cite news |last=Stefanovich |first=Olivia |date=January 21, 2021 |title=UN representative finds Canada's Indigenous people are 'disproportionately' affected by toxic waste |work=CBC |url=https://www.cbc.ca/news/politics/un-special-rapporteur-toxic-waste-findings-1.5164746 |access-date=November 8, 2023}} In response to this situation, some grassroots groups and movements have been formed in order to fight to change this imbalance. For example, ‘Land Back’ is an Indigenous-led movement that leads protests and demonstrations. Their goal is to help influence policy changes that would reclaim land for indigenous groups, allowing them to have control over how that land is used, extracted, and polluted.
