# The 50 largest Wholesale companies in Canada Tamtam tracks 114 Wholesale companies headquartered in Canada. This list ranks the 50 largest by number of employees on LinkedIn, led by Costco Wholesale Canada, Master and Emco Corporation: Plumbing, HVAC, Waterworks, Industrial, Irrigation, Fire Protection. Their median headcount is 359. Half of them were founded in 1952 or later. The most common headquarters are Calgary (5), Mississauga (4) and Burlington (3). This selection of wholesale companies in Canada includes large, established firms. Among them are Costco Wholesale Canada, a global retailer with warehouse club operations, and Master, a distributor in the HVACR industry. Emco Corporation specializes in plumbing, HVAC, and waterworks, while Uni-Select Inc. distributes automotive refinish products and aftermarket parts. Sonepar Canada and Nedco are prominent distributors of electrical products. The companies listed show a strong presence in the distribution of industrial, electrical, and automotive products. A notable pattern among these companies is their long history, with many established before the mid-20th century. Emco Corporation was founded in 1906, Grainger Canada in 1889, and Guillevin in 1906. This suggests a sector with deep roots and sustained operations in the Canadian economy. The headquarters are spread across several provinces, with a concentration in Ontario and Quebec. πŸ‡¨πŸ‡¦ Canada Β· 50 companies Β· Updated Nov 12, 2026 | # | Company | Industry | Headquarters | Employees | Founded | |---|---|---|---|---|---| | 1 | [Costco Wholesale Canada](https://www.tamtam.ai/c/costco-wholesale-canada) (costco.ca)

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.
