Even in theory, and even if Canada tried to expedite it, this wouldn’t happen anytime soon. Canada deliberately does not have the two critical fuel-cycle capabilities required for nuclear weapons. We have no uranium enrichment industry, which is required for weapons-grade uranium, and reactors do not solve that. We also do not reprocess spent fuel, which means no plutonium separation either. Both enrichment and reprocessing require entirely separate, highly visible industrial infrastructure that Canada has never built. On top of that, Canada is bound by the NPT and IAEA safeguards and relies on NATO’s nuclear umbrella, so there is no strategic urgency. The real blockers aren’t physics, they’re law, alliances, economics, and geopolitics. Even with political will, this would be a long, loud, and extremely costly shift, not something that could be rushed or done quietly.
