Do I still get full personal tax credits for the year I emigrate from Canada?

No, not the full amount for a full year, in the year you emigrate, you're filing as a part-year resident, and certain personal, non-refundable tax credits are prorated to reflect the portion of the year you were actually a Canadian resident, rather than being claimed in full as if you'd been resident the whole time. The idea is that credits meant to reflect a full year of Canadian residency shouldn't be given in full to someone who was only actually resident for part of it.

This affects your final return for the departure year specifically, alongside the deemed disposition reporting and any elections you're making, it's a separate mechanic from departure tax itself, but it's easy to overlook when the bigger, more attention-grabbing departure-tax numbers are the main focus of preparing that return. Getting the proration wrong, in either direction, can mean either overpaying or under-claiming credits you were genuinely entitled to for your period of residency.

Because the departure year's return already involves several moving pieces, deemed dispositions, possible elections, and now prorated credits, having it prepared carefully, ideally by someone experienced with emigration-year returns specifically, reduces the risk of errors on a return that's more complicated than an ordinary year.
