In 1998, TransCanada Pipelines merged with NOVA Corporation's pipeline business, keeping the TransCanada name and becoming "the fourth largest energy services company in North America".{{Cite web |title=TransCanada, Nova Complete Merger|url=https://www.naturalgasintel.com/articles/92796-transcanada-nova-complete-merger|publisher=Natural Gas Intelligence|date=1998-07-06|access-date=2020-03-01}}

Seeking to expand its presence in the United States, in 2016, TransCanada acquired Columbia Pipeline Group (CPG) for US$13 billion from NiSource's Shareholders. The CPG acquisition added a pipeline network in Pennsylvania and surrounding states, where the Marcellus and Utica shale gas formations are located.{{Cite news|url=http://business.financialpost.com/commodities/energy/transcanada-corp-to-acquire-columbia-pipeline-group-in-us13-billion-deal|title=TransCanada Corp to overhaul its business in US$13B acquisition of Columbia Pipeline Group|date=2016-03-18|work=Financial Post|access-date=2018-03-15|language=en-US}}

TC Energy's natural gas pipelines business builds, owns and operates a network of natural gas pipelines across North America that connects gas production to interconnects and end use markets. The company transports over 25% of continental daily natural gas demand through 91,900 km (57,100 mi) of pipelines. In addition, the company owns 535 Bcf of natural gas storage facilities, making TC Energy one of the largest natural gas storage providers in North America. This segment is TC Energy's largest segment, generating approximately two-thirds of the company's EBITDA in 2017. The Natural Gas Pipelines business is split into three operating segments: Canadian Natural Gas Pipelines, U.S. Natural Gas Pipelines, and Mexico Natural Gas Pipelines.

The major pipeline systems include:

• NGTL System (24,320 km) A wholly owned subsidiary, NOVA Gas Transmission Ltd., connects gas producers in the Western Canadian Sedimentary Basin with consumers and exports.{{Cite web |title=NGTL System |url=https://www.tcenergy.com/operations/natural-gas/ngtl-system/ |publisher=TC Energy |archive-url=https://web.archive.org/web/20200309000228/https://www.tcenergy.com/operations/natural-gas/ngtl-system/ |archive-date=2020-03-09|access-date=2020-03-09}} TC Energy has the largest and most extensive natural gas network in Alberta.{{cite news|title=TransCanada rule change raises ire of producers|agency=Financial Post|last=Morgan|first=Geoffrey|newspaper=Saskatchewan StarPhoenix|url=https://www.pressreader.com/canada/saskatoon-starphoenix/20171101/282226600986366|date=November 1, 2017}}
• Canadian Mainline (14,077 km) this pipeline serves as a long haul delivery system transporting natural gas from the Western Canadian Sedimentary Basin across Canada to Ontario and Québec to deliver gas to downstream Canadian and U.S. markets. The pipeline has evolved accommodate additional supply connections closer to its markets. The mainline is over 60 years old{{cite web|url=https://www.transcanada.com/en/operations/natural-gas/canadian-mainline/|title=TransCanada Canadian Mainline – Overview|website=www.transcanada.com}}
• Columbia Gas (18,113 km) This natural gas transportation system serves the Appalachian Basin, which contains the Marcellus and Utica plays, two of the largest natural gas shale plays in North America. The system also interconnects with other pipelines that provide access to the U.S. Northeast and the Gulf of Mexico.
• ANR Pipeline System (15,109 km) This pipeline system connects supply basins and markets throughout the U.S. Midwest, and south to the Gulf of Mexico. This includes connecting supply in Texas, Oklahoma, the Appalachian Basin and the Gulf of Mexico to markets in Wisconsin, Michigan, Illinois and Ohio. In addition, ANR has bi-directional capability on its Southeast Mainline and delivers gas produced from the Appalachian basin to customers throughout the Gulf Coast Region.
• Columbia Gulf (5,377 km) — This pipeline system was originally designed as a long haul delivery system transporting supply from the Gulf of Mexico to major demand markets in the U.S. Northeast. The pipeline is now transitioning to a north-to-south flow and expanding to accommodate new supply in the Appalachian Basin and its interconnects with Columbia Gas and other pipelines to deliver gas to various Gulf Coast markets.
• Mexico Pipeline Network (1,680 km) — This consists of a growing network of natural gas pipelines in Mexico.

Two TC Energy's Liquids pipelines connect Alberta crude oil supplies to U.S. refining markets., the Keystone Pipeline System and the Grand Rapids pipelines. The 460 km-Grand Rapids pipeline transports crude oil from the producing area northwest of Fort McMurray, Alberta, to the Edmonton/Heartland, Alberta market region. In October 2012, TransCanada formed a 50–50 CAD$3bn joint-venture with Phoenix Energy Holdings Ltd. (the Canadian subsidiary of PetroChina) to develop the 500 km Grand Rapids Pipeline.{{cite web|url=https://www.reuters.com/finance/stocks/TRP/key-developments/article/2631892|title=${Instrument_CompanyName} ${Instrument_Ric} Key Developments|author=Reuters staff|website=Reuters|access-date=6 October 2017}}

The 4,324 km-Keystone Pipeline System transports crude oil from Hardisty, Alberta, to U.S. markets at Wood River and Patoka, Illinois, Cushing, Oklahoma, and the U.S. Gulf Coast. The Keystone System transports approximately 20% of Western Canadian crude oil to export markets. The Keystone Pipeline has had three significant leaks since it opened in 2010. It has leaked approximately 400 barrels in North Dakota in 2011 and South Dakota in 2016, and approximately 5000 barrels in South Dakota in 2017.{{Cite news|url=https://www.reuters.com/article/us-usa-pipeline-keystone-spills/keystones-existing-pipeline-spills-far-more-than-predicted-to-regulators-idUSKBN1DR1CS|title=Keystone's existing pipeline spills far more than predicted to...|date= 2017-11-27|work=Reuters|access-date=2018-03-15}}

A third pipeline, the 1,906 km-long Keystone XL Pipeline — which is an expansion of the Keystone Pipeline System — began construction in 2020. When completed, the Keystone XL Pipeline will transport 830,000 barrels of Athabasca oil sands crude oil per day from the Hardisty, Alberta to Steele City, Nebraska.

In response to Alberta's financial support, in March, TC Energy "approved construction of the US$8-billion project to transport up to 830,000 barrels per day of oil." According to a Canadian Press March 31, 2020 article Premier Kenney estimated that "1,400 direct and 5,400 indirect jobs" would be created in Alberta during construction. In September 2020, TC Energy announced that it would be restructuring some of its gas pipeline operations in Alberta.

In April, shortly after construction on Keystone XL began, Judge Brian M. Morris of the Federal District Court in Montana suspended the United States Army Corps of Engineers (USACE)'s program allowing permits for pipelines to cross waterways, in spite of the Clean Water Act (CWA). Judge Morris said that the USACE pipeline permits "posed a threat to endangered species" and its reauthorization in 2017, had been improper. In July 2020, the Supreme Court of the United States declined to block Judge Morris' ruling, effectively halting all construction on the XL Pipeline.{{Cite news| issn = 0362-4331| last = Liptak| first = Adam| title = Supreme Court Won't Block Ruling to Halt Work on Keystone XL Pipeline| work = The New York Times| access-date = September 29, 2020| date = July 6, 2020| url = https://www.nytimes.com/2020/07/06/us/politics/supreme-court-keystone-xl-pipeline.html}}

In 2019 TransCanada aided the drafting of anti-protest legislation in South Dakota. The legislation, which Governor Kristi Noem signed into law in March 2019, created a fund to cover the costs of policing pipeline protests, and was accompanied by another law which sought to raise revenue for the fund by creating civil penalties for advising, directing, or encouraging persons participating in rioting. In response to the law Noem was sued by the Indigenous Environmental Network, Sierra Club, and other groups, who argued the laws violate First Amendment rights by incentivizing the state to sue protesters.{{cite web|url=https://theintercept.com/2019/05/23/pipeline-protest-laws-louisiana-south-dakota/|title=Pipeline Opponents Strike Back Against Anti-Protest Laws|date=May 23, 2019|accessdate=March 24, 2021|work=The Intercept|first=Alleen|last=Brown}}
