If you have tracking number check with Canada Post. But I believe they are sent in an envelope without any tracking (cost more!). If you do not get it at the end on month, contact agent for replacement.
I don't know if it still works as a method but if you got an order number then you can go to CanadaPost and use that order number and then it will ask for a corresponding postal code and maybe it will show you some information. I'd be interested to hear your results if it is still a method.
