Quebec is different as it has its own forms for everything.
When I select a spouse to assign the medical expenses to, it ONLY changes it on the Federal form. And there is no way to change the Quebec provincial selection. As it happens, Quebec makes you deduct 3% of both spouses income from the medical expenses, so changing spouses makes little difference. Unless of course the lower income spouse doesn't need the deductions. I think this is a bug, though I can't say that this overly impacted me this year.
