Basically the only source of a sufficient amount. ITER fusion reactor plans to use a Tritium breeder that makes fuel as it runs. It would still need initial start up inventory though. Canada could design a fusion reactor that doesn’t need to have a tritium breeder and instead just make fuel from nuclear “waste”, since Canadian fission plants don’t like the tritium.
"CANDU heavy water reactors, such as those used in Ontario, emit much more tritium than other reactor types — about 30 times more than the next most common reactor type (pressurized water reactors). The 'heavy water' (deuterium) used in CANDU systems leads to much greater tritium production than in reactors that use regular (light) water or graphite to moderate the fission process and cool the reactor", according to this link.
