Lost old passport. New passport, valid work permit in old passport. Am I cooked?

[oswalt]

I have a valid work permit until 2027, I lost my passport and got a new one while living in Canada. I just left the country for a month with my new passport. Am I going to be able to reenter without having both the old and new passport?

I have photo copies of my old passport - not sure this matters much

A work permit lets you enter Canada. You need a TRV. You need to replace it. Show that you filed a police report for the lost passport too.
