This might be a bit of an odd question so here is the run down:

• I was born in France
• I live in Canada and am a citizen
• I own a valid French passport
• My Canadian passport as recently expired
• I need to go to the US over the weekend and won't have a Canadian passport on time.

I'm planning on going in the US with my French passport, and pay for the visa. So far no big deals.

What will happen when I come back to Canada with my French passport and/or my expired Canadian passport ? What could happen ? Could they refuse me entry ? Force me to renew my passport on the spot ?

Thanks !
