The multinational companies in Alberta listed here are primarily large corporations, with the largest having 180,000 employees. Many operate in the oil and gas sector, such as Suncor, which focuses on oil sands development, and Enbridge, a provider of energy infrastructure. Other notable companies include Stantec, offering engineering and architectural services, and PCL Construction, an independent construction firm.
A significant pattern observed is the concentration of headquarters in Calgary, which hosts companies like Suncor, Enbridge, Canadian Natural Resources Limited, and WestJet, an airline offering scheduled flights.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
