If you live in Ontario and you've decided to pay out-of-pocket for surgery within Canada to get faster access to care, then you'll need to get surgery done out-of-province. This article explains the reasons why, and what your options are.
For educational purposes only. Not legal or medical advice.

To be clear: it is perfectly legal to seek private surgery in Canada, but, for Ontarians, you cannot do so within Ontario because of the current regulatory framework.
It's a quirk of Canada's private healthcare system that patients must generally travel out-of-province for surgery. For Ontario specifically, if the surgery is something OHIP normally covers (like a knee replacement or hernia repair), you cannot pay a clinic in Ontario to do it privately.
In other provinces, doctors have the option to opt out of the public healthcare system, and can see patients within province, but that is not the case in Ontario.
You can still pay privately in Ontario for things that OHIP doesn’t cover (mostly cosmetic or optional procedures).
They travel. Ontarians fly or drive to another province (or country) where private-pay for that specific surgery is allowed.

When deciding where to go, there are three main things to consider: surgeon expertise, support, and aftercare.
One of the benefits of private surgery is that you can choose your surgeon. I recommend booking several consults with surgeons who specialize in your surgery (consults cost $150 - $350 each, but it's worth it to explore your options and feel good about your choice).
In your research and consultations, look for:
The right surgeon can make a less convenient destination worth it, but the another important thing to keep in mind is somewhere you’ll have reliable help for the first few days or week.
Depending on the surgery, you may need substantial help immediately post-surgery to manage meals, meds, mobility, wound care basics, and transport to follow-ups—crucial for older adults or anyone with limited mobility.

Travel and recovery logistics can be as important as the surgery itself.
Québec is a logical choice for many Ontarians because of proximity. Many major cities (such as Toronto, Mississauga, Hamilton) are a train ride away from Montréal. If you're in Ottawa or Kingston, then Montréal and Sherbrooke are short drives away.

Depending on how major your surgery, this commute could be a critical consideration. Taking the train or getting a ride with a friend or family member can be much more desirable commutes than flying.
Québec also has the most extensive private surgical system in the country because of its looser regulatory and legal framework that's enabled private healthcare growth alongside the public system. Unlike other provinces, Québec allows physicians to choose to participate in the public or private systems, or offer both.
A common concern is the language barrier. In Québec, French is required of surgeons, English is not. That said, this won't present a problem for someone desiring English care. Private surgeons and clinics who cater to patients out of province generally have rigorous standards around language proficiency, and you'll be able to determine for yourself on your consult with the surgeon.

Alberta appeals to Ontarians seeking private surgery due to mature independent surgical facilities in Calgary and Edmonton. Outside of Québec, Alberta has the most extensive private healthcare system—some 20% of surgeries are done privately.
Surgery in Alberta will require a ~4-5 hour flight (it's a 33-40 hour drive, which isn't ideal even in top health), with the benefit of several direct flight options. The roads in Calgary and Edmonton are wide and relatively uncongested, which makes commuting around the city less of a hassle.
The furthest option—at least a 5 hour flight to Vancouver or Kamloops—British Columbia may make sense for you because it has one of the highest concentrations of specialist surgeons in the country.

Manitoba and Saskatchewan are perfectly good options too depending on your surgery, but the pool of specialists is substantially smaller. The Maritimes and Territories have limited to no private practice for medically necessary surgeries.
For Ontarians, faster private surgery means traveling out of province. Make your choice for where to go based on surgeon expertise, support available, and aftercare considerations. There are lots of great options available, but depend on your situation.
