According to the U.S. Energy Information Administration, Canada was home to the world’s fifth-largest energy production industry in 2023 (its latest information available). Globally, it is the fifth-largest producer and sixth-largest exporter of natural gas.

Private and public companies of all sizes engage in natural gas production across the Canadian landscape, with average output reaching 19 billion cubic feet per day in 2025. While some of these firms are integrated oil and gas companies with extensive operations in upstream and downstream industries, others focus on upstream exploration and production.

In 2025, many of the companies that make up Canada’s oil and gas industry saw revenues in the billions. Below are some of the largest companies in Canada whose business involves natural gas. All figures are in Canadian dollars. Investors looking to gain exposure to the Canadian energy market could consider some of the large corporations below as a way to diversify their portfolio.

Of course, like all energy companies, these entities are subject to price volatility in the energy market, global supply and demand risk, changing political regulations in the countries where their basins are located, and geological risks.
