You obviously get more points from masters but undergraduate students do have a higher chance of getting a job than a masters student. I know a bunch of guys who finished masters here at UofT but didn't get a job. On the other hand, The undergrad students were getting multiple job offers. Canadian employers consider bachelor degrees outside Canada to be non viable and try their best to hire employees wive graduated with Bachelors from a Canadian university.
One of reason is that, You have a higher chance of getting a Peng with an undergraduate from Canada rather than postgraduate. Look at the statistics. Employers look for Peng candidates because they've been certified by the provincial board.
Try your best to take a few undergraduate courses or TA most undergraduate courses in order woo employers during interview.
