Human Resources is a highly regulated profession in Canada. It's not easy to get into even if you have good experience and studies abroad. You need to be certified here as HR Professional by the recognized authorities. But, it's not impossible either. You have to be prepared and keep trying to get into it, as I am at the moment.
There are a few 'Bridging Programs' for internationally trained professionals in Canada. I'm trying to get into one of the programs now. Perhaps it's worth for you too to inquire.

Good luck!
