Hove you been out the country with your current passport?
If Yes, no need to cancel your "户口". If not, you may need to.
Canada is clean. If you're not afraid of "foot-mouth" dicease it is okay not to do any prevention.

I have used my passport several times and I am not afraid of anything. So do you mean that I needn't do anything else... ?
