Beggars can't be choosers. The alternative (waiting lists so long that people die waiting) isn't tenable either.
Once the government changes and the incoming government removes a lot of restrictions on provinces, I expect we'll see substantial pressure on professions like medicine to make licensing much more straightforward. No more gatekeeping just to protect their negotiating power with bureaucracy.
Credential recognition to one side (important issue though it is); a big problem is the lack of residency opportunities for doctors, be they domestically trained or foreign trained. To my understanding that's a straight-up funding question for the provinces.
Likewise, there is a lesser requirement vs residency for those who are/were practicing physicians in other countries, which is the Practical Assessment (generally 12 weeks under supervision, with the supervisor being able to waive the residency requirement at the conclusion of said exercise.)
Ontario had such a program a few years ago, then nixed it, and only just restarted it, but with far fewer opportunities than demand would indicate.
Several other provinces have been doing these (practical assessments) for years now and doing so in relatively higher numbers than Ontario when adjusted for population.
I don't believe the federal government is an obstacle in these cases, its Ontario (and other provinces as applicable) that have chosen not to provide sufficient opportunities for professional accreditation.

Likewise, of course, Ontario has graduated far too few doctors for decades, a decision that goes back to the Rae government in Ontario in the 90s who came to the strange conclusion that graduating more doctors automatically meant higher healthcare costs, so they froze the number of study places; something no subsequent government undid until the last 18 months ( well more spots/schools are approved, but not yet operating) The Harris gov't also deregulated medical school tuition in 1998 sending it skyrocketing and seeing applications from middle-income households drop off markedly.

None of which takes away the legitimate issue that far more medical school credentials should be recognized in full.
