1) Aluminum ore is not formed in Quebec (why not?) 2)but aluminum ore is smelted into aluminum in Quebec. Why?
Bauxite is the most common aluminum ore. Bauxite forms in tropical regions because its formation requires intense weathering conditions (lots of frequent rainfall) with a very good drainage. Even if, due to continental drift, Quebec was once in a tropical region, it is highly unlikely that bauxite would have formed there because almost all of Quebec sits on the Canadian Shield. The Canadian Shield is a large region of very, very old rock that can be thought of as mostly monolithic and quite flat. Its monolithic nature makes it difficult to weather, and its flatness means that it doesn't drain as well as is needed to form bauxite. Smelting bauxite requires enormous amounts of electricity - not just any energy, but electricity. Quebec has enough hydroelectric resources to make this practical.
