What SN Diesel Service, Division of Tokmakjian Inc. does

SN Diesel Service, a division of Tokmakjian Inc., is a heavy-duty diesel equipment repair and parts distribution business operating from a 65,000 sq ft facility in Concord, Ontario, with over 40 years of operating history since its founding in 1976. The company operates four core service lines: Heavy Duty Repairs (engine and transmission rebuilding as an authorized Cummins dealer, with specialized capabilities for Allison and Voith transmissions and an in-house engine dyno for performance validation), Bus Garage services (running repairs, brakes, suspension, steering, air conditioning, and tires), Body Shop services (collision repair, panel replacement, and an oversized paint booth), and a Parts Department distributing over 10,000 SKUs from a newly renovated 20,000 sq ft warehouse with wholesale pricing for qualified buyers.

The business serves commercial fleet operators, bus companies, and truck owners in Ontario through a direct-to-consumer go-to-market model: customers engage via phone, toll-free number, or walk-in at the 28-bay service facility. Revenue is generated through hardware parts sales and professional repair services, with no subscription or recurring digital revenue model. The company operates 24 hours per day, 6 days per week to minimize customer fleet downtime. It is privately held with no external funding, no mobile app, no public API, and no digital product surface.

In 2017, SN Diesel Service announced a rebranding to TOK Performance as part of the parent Tokmakjian Inc. transportation group's brand consolidation strategy. The broader TOK Group includes TOK Transit, CAN-AR Coach, and CABSS, positioning SN Diesel within a diversified transportation conglomerate. The company is not exposed to AI or software-driven product evolution; its value proposition rests on physical infrastructure, OEM-authorized service capabilities, and long-tenured customer relationships in the Greater Toronto Area diesel fleet market.
