That's not true... She will be able but with a lot of hard work but It's almost impossible... Here are some DR's replies on a forum:

OK. I am a doctor myself from South Africa. When I came to Canada I had to work through a painstaking 3 year process to validate my medical license here. I was sent to a small city north of Regina for two rotations after I had finished the never ending exams, but finally I was awarded with my license.
Thus, it is possible, however the process is so painstaking that you may see medical doctors from Poland, Mexico and even the USA working in real state and even as taxi drivers.
Do your homework first before moving here. I do knot that the Provice of Ontario is changing the rules to speed up the validation of foreign medical credentials, but the process may take a while.

I came to Canada as a pediatrician. Now I run a catering service. Business it is not bad at all now, but it took me more than 5 years of frustrations to realize that I needed to do something else.
Canada is a tough place for foreign doctors. I do not know if all places are the same, but here is almost impossible.

Like you could see the second person ended up doing catering because they got frustrated, and the first person eventually got their license.
