Thinking of delaying graduation

I will be arriving in Canada in the summer months, I have the chance to take my degree this year or next year, March.

I would be in a PR status, After a few months I would love to work as a clinical assistant, While I'm preparing for the exams  for residency in the states and Canada , do they hire medical students for paid positions or do I have to take my degree so I'm considered a graduate instead of a student to apply for that sort of a job? this will be in Ontario.

thankyou
