# List of chemical companies in Canada

Tamtam tracks 143 chemical companies headquartered in Canada. This list ranks the 50 largest by number of employees on LinkedIn, led by Nutrien, Imperial Oil and ArcelorMittal Dofasco. Their median headcount is 835. Half of them were founded in 1973 or later. The most common headquarters are Toronto (8), Calgary (6) and Montreal (4).

This selection of Canadian chemical companies includes major players in agricultural chemicals, oil and gas, and diversified manufacturing. Nutrien, founded in 2018, specializes in agricultural nutrients. Imperial Oil, established in 1880, focuses on petroleum refining and petrochemicals. ArcelorMittal Dofasco produces sustainable steel products, while NOVA Chemicals designs polyethylene resins. Plasman is a global leader in automotive components, and Methanex Corporation is a major methanol producer. Kruger Inc. operates in pulp and paper, packaging, and green energy. Shawcor provides solutions for the energy industry.

A notable pattern is the concentration of headquarters in Calgary, which hosts Imperial Oil, Agrium, NOVA Chemicals, SECURE, and Lafarge Canada. Many of these companies, such as Imperial Oil (1880), Kruger Inc. (1904), and Agrium (1931), have long histories, while others like Nutrien (2018) and SECURE (2007) are more recent.

## 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 12, 2026.
