Really depends on where you graduate from, your specialist qualification and work experience. Canada (like many other countries) has it's own strict medical profession governing bodies. Best you visit their medical council website and find out if you're recognized as a surgeon there. Best case scenario is, if you're fully recognized, then moving there and getting a job there is easy. At the other end of the spectrum, if you're not recognized at all, then be prepared to start from the bottom as an intern.
