Thank you for your question.
Medical school enrollment has increased substantially in the last few years. In fact, first-year undergraduate medical school enrollment has increased by 60% over the last decade.
The provinces and the territories, which have responsibility for health human resources and deciding how many seats will be made available, have increased the seats by over 1,000 in the decade between 2000 and 2010. First-year residency positions have increased by 84%.
I think part of what you may be describing is the very competitive nature of people who wish to go to medical school. It's commendable that young people want to go into medicine, but there are a finite number of resources the provinces and territories can dedicate to their health system functioning. I think their cooperation with their medical faculties results in a set number of residencies becoming available.
