Look at university websites for medical school tuition rates and add in cost of living for that city. I'm not sure what you mean to become a doctor then a specialized doctor. You become a doctor when you finish medical school then you do a residency that is anywhere from 2-6+ years long depending on what you are specializing in. During residency you receive an income which varies between about 55k and 70k depending on which province and which year of residency you are in.
Are you from outside of Canada? If you are, you will be paying international student rates. There is no option for you to pay the low Canadian tuition rates. I suggest you study in the United States. Canada's healthcare is socialized with a small number of hospitals and medical centres. The government limits to hiring a small number of people (unless you plan to open your own practice).
Both my gf and I graduated med school with about 130k in debt. She's worked her debt down to 80k after 3 years of residency. I increased mine significantly due to a home purchase and related investments. Mine would also be about 80k now if I sold my assets.
