Copper C110 (Electrolytic Tough Pitch) in Canadian Manufacturing
C110 ETP copper is the standard high-conductivity copper for electrical bus bars, terminals, heat exchangers, and thermal management hardware. Canada is one of the world's top copper producers — major Quebec, Ontario, and BC mines feed domestic refining capacity that supplies copper rod, bar, plate, and sheet stock through national distributors.
Copper C110 in Canadian Manufacturing
Canada is one of the world’s top ten refined copper producers. The country mines, smelts, and refines copper at industrial scale — most prominently through Glencore’s Horne smelter and CCR refinery in Quebec, Vale’s Sudbury operations, and Teck’s Trail metallurgical complex. That puts Canadian buyers close to the supply chain for C110 mill product.
Why C110 Where Other Metals Won’t Do
Copper does two things uniquely well: conduct electricity (second only to silver, at vastly lower cost) and conduct heat (also second only to silver). For any application where electrical or thermal conductivity is the critical spec, C110 is the answer. Switchgear bus bars, EV battery interconnects, motor windings (as wire), heat exchangers, and high-current terminals all rely on its properties.
It also forms a stable patina in outdoor exposure (the green of a weathered copper roof) and resists marine corrosion well, which is why architectural and marine applications use it despite the cost.
Working With Canadian Copper Shops
Most fabrication of C110 in Canada is done by specialty electrical or thermal-management shops, not general machining houses. Bus bar fabrication, plate forming, laser welding of cooling channels, and electroplating (silver or tin for switchgear contact surfaces) are concentrated in the Toronto–Mississauga, Montreal, and Vancouver clusters.
For machined parts, plan ahead: copper consumes tooling, demands sharp cutters, and benefits from the half-hard temper. Many Canadian shops will substitute leaded copper (C145 tellurium copper or C147) where the conductivity penalty is acceptable, in exchange for much better machinability — confirm whether your application can tolerate the substitution.

Where It's Made in Canada
Canada produces roughly 600,000 tonnes of refined copper annually. Major operations include Glencore's Horne smelter (Rouyn-Noranda, QC) and CCR refinery (Montréal-Est, QC), Vale's Sudbury operations (ON), and Teck's Trail facility (BC) which produces electrolytic copper from concentrate. Finished C110 mill products (bus bar, sheet, rod) are distributed by Russel Metals, Samuel, Wieland Canada, and specialty electrical-grade copper suppliers.
