The annual output of 'extractable' Helium-3 on Earth is around 840,000,000 m^3. This comes out at a total mass of 103,000 metric tonnes per year. Canada could produce up to ~5% of this total. The cost of extraction is also so ridiculously high it would negate the energy that would be produced in a crude fusion reactor...

Put simply Helium-3 production on Earth really isn't that possible.
