I'll share my wife's experiences, who is an international medical graduate.
We arrived in August 2021, I was a student, and she had an open work permit. Her English was not that good then, probably at an intermediate level. She started looking for a job. Because of her English level, she wasn't looking for a health administrative assistant job, so she started looking for something related to caregiving for elders. After a month of sending resumes, she never got a single call, so she decided to look for something different and found a job in a warehouse as an order picker. After a few months, she met someone who worked as a home support worker and was also a physician, so her friend referred her, and she finally got a job in that field. Her English was better now.
She worked as a HWS for 6 months. We then moved to a different city after I finished my studies, and she again started looking for a job in a similar field. This time, she started getting a lot of offers, probably because of her previous experience. She finally got a job as a personal support worker, which is usually better paid than a HSW. Most places require a PSW certificate for this job, but this place said that her previous experience and her international diploma were enough for her to perform the job. She's been there for 3 months now.
We're hoping to get PR by the end of this year after I complete my 1-year experience. She plans to study something after we get PR (cheaper when you're PR than if you're an international student). She first thought about getting into the whole physician license path, but as others have mentioned in this thread, it is extremely difficult. She is now thinking about a master's degree in something like physical therapy or kinesiology. However, those are not easy to get into either (still not as hard as getting a physician's license). A physician assistant is also an option to consider. The last resource would be getting a graduate degree in health administration, which is probably an easier path and one many IMGs take from what we've seen.
The journey for an IMG in Canada is not easy.
