20 Years Export Experience • 1xxx–7xxx Alloy Series • Factory-Direct, No Middleman
Canada is one of the world’s largest producers of primary aluminum, powered by cheap hydroelectricity in Quebec — but that scale doesn’t carry through to finished sheet and plate the way most buyers assume. The country smelts enormous volumes of raw aluminum, yet has only one large-scale flat-rolled mill in operation. A lot of the metal Canada produces leaves as ingot and comes back later as finished sheet from somewhere else. Here’s how Canada’s leading aluminum producers, mills, and fabricators compare, and where OEM sheet and plate sourcing fits into that picture.

Canada’s Aluminum Producers & Processors
1. Novelis
Base: Kingston, Ontario
Novelis runs the only large-scale flat-rolled aluminum mill in Canada, handling cold rolling, coil finishing, and slitting. The Kingston plant is central to North American automotive and beverage-can packaging supply chains, and Novelis is also a global leader in high-recycled-content aluminum.
2. Rio Tinto Aluminium
Base: Alma and Arvida, Quebec; Kitimat, British Columbia
Rio Tinto operates several of Canada’s primary aluminum smelters, drawing on Quebec’s hydroelectric power to produce metal with one of the lowest carbon footprints per tonne in the world. Its output is primary aluminum ingot and billet — the raw material other companies roll, extrude, or cast into finished products.
3. Alcoa
Base: Baie-Comeau and Deschambault, Quebec
Alcoa operates major primary smelting capacity in Quebec, contributing to Canada’s position as a global source of hydro-powered, low-carbon primary aluminum.
4. Aluminerie Alouette
Founded: 1992 | Base: Sept-Îles, Quebec
Aluminerie Alouette operates the largest primary aluminum smelter in the Americas, also powered by Quebec hydroelectricity.
5. ELYSIS
Founded: 2018, as an Alcoa–Rio Tinto joint venture | Base: Quebec (pilot cells at Alma and Arvida)
ELYSIS is developing inert-anode smelting technology intended to eliminate direct CO2 emissions from primary aluminum production, with commercial deployment targeted for later this decade.
6. Kaiser Aluminum
Base: US-headquartered, with facilities and sales operations serving Canada
Kaiser supplies engineered, semi-fabricated aluminum mill products across North America, with a focus on heat-treated and specialty alloys for aerospace, automotive, and industrial applications. It is not a Canadian-based manufacturer, but a significant supplier into the Canadian market.
7. Diversified Ulbrich of Canada
Base: Ontario
Diversified Ulbrich distributes and processes aluminum sheet across multiple grades — including 1100, 3003, 5052, 5083, and 6061 among others — with secondary services such as slitting, shearing, annealing, and heat treating.
8. Johnson Bros. Roll Forming Co.
Founded: 1948 | Base: Ontario
Johnson Bros. manufactures roll-formed aluminum shapes, channels, angles, and tubing rather than flat sheet, working from polished, anodized, or clad aluminum stock.
9. Spectra Aluminum
Founded: 1978 | Base: Bradford, Ontario
Spectra is a family-owned aluminum extrusion and fabrication business operating multiple facilities in southern Ontario, offering anodizing, painting, and finishing alongside extrusion. Like most Canadian fabricators, Spectra sources its raw aluminum billet and stock from established mills rather than rolling its own sheet.
10. RSC
Type: OEM aluminum sheet & plate manufacturer | Experience: 20 years export experience | Base: Tianjin, China
RSC (Tianjin Ruishengchang) manufactures and exports aluminum sheet, plate, rod, tube, and coil directly from its own Tianjin facility, covering the 1xxx through 7xxx alloy series. Unlike the domestic Canadian companies above, it does not sell finished consumer products under its own retail brand — it produces to the buyer’s specification, with controlled thickness, improved flatness, stress-relieved options, and cut-to-size delivery, and exports to a growing list of markets including Brazil, Mexico, Turkey, Saudi Arabia, and the US.
Why Canada Exports Aluminum Metal But Imports Much of Its Sheet
This is the part of the supply chain most buyers miss: Canada’s aluminum strength is concentrated upstream, in primary smelting. Quebec’s cheap hydroelectric power makes it one of the most competitive places on earth to produce raw aluminum, and companies like Rio Tinto, Alcoa, and Aluminerie Alouette do exactly that at enormous scale. But turning that raw metal into finished flat-rolled sheet and plate is a separate, capital-intensive process — and Canada has only one large-scale mill set up to do it domestically. The practical result is that a meaningful share of Canadian-smelted aluminum leaves the country as ingot and billet, while a meaningful share of the finished sheet and plate used by Canadian manufacturers arrives from mills outside the country. Being a major aluminum-producing nation and being self-sufficient in finished sheet turn out to be two different things.
Sourcing Custom Aluminum Sheet Through an OEM Partner
If your project needs standard flat-rolled sheet in common alloys, Novelis and Canada’s distributor network cover that ground directly. If you need a specific alloy, thickness tolerance, temper, or cut-to-size format that doesn’t match what’s sitting in domestic mill inventory, an OEM partner works from your exact specification rather than a fixed product catalog. This matters more for aluminum sheet than for many other materials, precisely because Canada’s own flat-rolling capacity is so concentrated in one facility — when that spec or volume doesn’t fit what Kingston is set up to run, sourcing from an OEM mill becomes the more direct path rather than a workaround.
FAQ
Does Canada manufacture its own aluminum sheet?
Some. Novelis operates Canada’s only large-scale flat-rolled aluminum mill, in Kingston, Ontario. Most of Canada’s aluminum industry, however, is concentrated in primary smelting rather than sheet rolling, so a significant share of finished sheet and plate used domestically is sourced from mills outside Canada.
What standard governs aluminum sheet and plate specifications?
ASTM B209/B209M is the standard specification most commonly referenced for aluminum and aluminum-alloy flat sheet, coiled sheet, and plate, covering alloy, temper, and finish requirements. Buyers sourcing sheet from any manufacturer, domestic or OEM, should confirm the product is certified against this specification.
Is it cheaper to buy aluminum sheet from a Canadian mill or an OEM partner overseas?
It depends on the alloy, thickness, and order volume. Standard alloys in common thicknesses are often available quickly through Canadian distributors. Custom specifications, less common alloys, or large bulk orders are frequently more cost-effective and flexible through an OEM partner working from your exact spec.
Conclusion
Canada’s aluminum industry is genuinely world-class at the smelting stage, but that scale doesn’t automatically translate into domestic flat-rolled sheet capacity — Kingston is doing a lot of the country’s heavy lifting on its own. If you need standard sheet in common alloys, Canada’s mill and distributor network is worth comparing directly. If you need a custom alloy, tolerance, or cut-to-size specification, an OEM partner is generally the more direct path to a product built to your own requirements.
