I am a resident of the Yukon, currently a master's student in Ontario. Where do I file prov/terr taxes? Do I claim moving expenses?

I am still a resident of the Yukon (driver's licence, health, etc.) I have lived in Ontario since Sept 2022, and drove here. When I say I lived in Ontario on Dec 31, 2022 it is interpreted as my being an Ontario resident, but I was under the impression I am still a Yukon resident.
