# List of manufacturers in Calgary

Tamtam tracks 50 manufacturers headquartered in Calgary. This list ranks the 30 largest by number of employees on LinkedIn, led by Cenovus Energy, Imperial Oil and Enerflex Ltd.. Their median headcount is 405. Half of them were founded in 1988 or later.

The manufacturing companies in Calgary are primarily established firms, with a strong presence in the oil and gas sector. Cenovus Energy, for example, is an integrated energy company with operations across North America and Asia Pacific. Imperial Oil, founded in 1880, specializes in petroleum refining and crude oil production. Enerflex Ltd. provides energy infrastructure and transition solutions, while Agrium focuses on sustainable food production.

A notable pattern among these companies is the significant representation of the oil and gas industry, alongside chemical manufacturing and construction. Companies like NOVA Chemicals produce polyethylene resins, and Lafarge Canada provides sustainable construction materials. This suggests a concentration of heavy industry and resource-based manufacturing in the region, with many companies having long operational histories.

## 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.
