S asked:
Being a international medical graduate, I need to take the medical license tests in North America and applying for residency. To be qualified, I have to supply reference letters from medical professors and hands on medical working experience. Specialists’ offices in Toronto area will be the opitimal choice here. Can anyone make a suggestion where I should start with?

just pick up the phone and start calling every possible one. Ask to talk to HR. Ask for an application, don’t say “are you hiring.”
Unfortunately much of the medical world has yet to catch up to the internet, so the phone is the best way to go.
Make ur search really broad, have the yellow pages in ur hand, look for dr’s offices close to u and submit resumes to them…im sure they will respond to u..it might help to volunteer with them first so they can see what u can do first being an international medical graduate.
