Entry signal — what decides who wins here
Structure decidesThe binding constraint is not executional. Being better than the incumbent does not, by itself, get you in — this one is cleared with capital, an asset, or a permission.
Come with the asset, or buy the business that owns it. Plant, fleet, land or quota decide this market before any operating skill does. Operators here are bought, not started.
Measured, not forecast: the share of US establishments opening in one year that were still active later. It counts good operators and bad ones together, which is exactly why it is the honest answer to “what are the odds”. It is for the whole sector rather than this market, and the ten-year figure comes from an older cohort because no younger one has reached ten years.
This is not a probability of success, and it is not a verdict on you. No survival probability is published per market, and inventing one would be worse than saying so. What the bar reads is how much of the outcome sits inside an operator's control: green means the hurdles are ones a better operator clears, red means the binding constraint is capital, an asset or a permission rather than execution. Someone arriving with an advantage this screen did not assume can win a market shown in red.

The binding constraint — capital intensity
Canada is a serious aluminum country — about 3.3 million tonnes of primary metal in 2024 from ten smelters, nine of them in Quebec, and C$17.4B of aluminum exports, 91% to the United States [A]. The pre-screen called smelting "power-contract economics", which is true and incomplete: the power contract decides whether a smelter lives, but the pot line decides whether anyone but a major can build one. Rio Tinto has just priced that. In 2023 it approved 96 new AP60 pots at its Saguenay complex for US$1.1B, adding about 160,000 tonnes a year; by the time commissioning began in 2026 the company was describing a US$1.5B expansion [A]. That is roughly US$9,400 per tonne of annual capacity, for a brownfield addition by the owner of the technology, on a site that already had the power, the port and the alumina. A greenfield entrant has none of those and would need a multi-decade hydro block that Quebec allocates as industrial policy, not as a product for sale. The rest of the group — rolling, extruding, alloying, secondary remelt — is where most of the 99 Canadian establishments sit, and the size bands are bimodal: 41 have fewer than ten employees, 25 have a hundred or more. Extrusion is the conceivable entry point, a press and a die shop serving window, trailer and solar-racking makers. It was not examined here, and nothing in this record should be read as a verdict on it. It would need its own screen, and that screen would start from billet supply: the press buys its metal from the same smelter owners at the exchange price plus a regional premium, and sells a shape its customer can re-quote.
Primary aluminum is priced on the London Metal Exchange plus a regional delivery premium and moves across borders as a matter of course — 91% of Canadian aluminum exports by value go to the United States. A smelter competes with every other smelter on the cost curve, wherever it is; its location matters only through what it pays for power.
Who you would be competing with
The operators already at scale here, and whoever is buying these businesses. In most of these industries the competition an entrant meets is local, so this is who sets the terms rather than a list of everyone in the trade.
Financials & market size — sourced
Figures that came from a filing, a results release or reputable reporting, each carrying its evidence tier.
Market size, derived
Built from the competitor set upward rather than quoted from a forecast. Published TAMs in these categories are frequently reverse-engineered from each other, so any published figure is checked against the vendor arithmetic rather than trusted on its own.
Disclosed revenue from 1 of 4 named vendors. The market is at least this large.
No vendor has both a disclosed revenue and a published share.
Only a revenue floor is known — the true market is larger by whatever the undisclosed vendors earn.

Evidence
Evidence. Establishment counts are Statistics Canada (December 2023) and US County Business Patterns (2022) [A]. Production, smelter count and export figures were read on Natural Resources Canada's aluminum facts page [A]. The AP60 figures were read in Rio Tinto's June 2023 release and in its 2026 commissioning release as filed on Form 6-K [A]; the two cost figures are both shown because they differ, and the per-tonne figure is the analyst's division, tiered B for that reason. Not sourced: any power-contract price, any smelter's margin, and anything at all about extruders, rollers or secondary remelters — no listed extruder's segment results were opened. The statement that Quebec allocates large power blocks as policy is general knowledge, not a cited rule. The cut factor is analyst judgment and applies to smelting only. The competitive field was added in a later pass: Alcoa's FY2025 revenue, its facility-by-facility Canadian and global smelting capacity and its idle capacity were read in Alcoa Corporation's 2025 Form 10-K, filed 26 February 2026 [A]; the Canadian share of Alcoa's nameplate is the analyst's arithmetic [B]. Rio Tinto's own revenue was not opened, and Aluminerie Alouette and the downstream rollers and extruders are named from general knowledge and tiered UNVERIFIED there.
