Would also look to see whether recertification will actually be possible. Some specialist have no chance of recertification because open residency spots will not be available. Many IMGs never work as physicians when they move to Canada because it is usually a long and expensive process with no guarantees of ever being able to practice. What kind of doctor are you?
Would spend a lot of time doing your research and consider immigrating to other countries where you are more likely to be able to practice medicine with a lot less hassle.
