Ontario and BC may be problematic
As of last month, Ontario Flight Schools are being put under the thumb of the Private Career Colleges Act (same as for hairdressers and truck drivers) for Commercial and Flight Instructor courses. The smaller operations are unable to deal with the bureaucracy and fees and are either dropping these programs or going out of business altogether.
BC has had the same thing going on for a bit longer and I hear there is a court challenge under way.
The extra costs will be passed on to the student of course; so, check the Ontario and BC operations for all the fees.
One school I know will be charging an enrollment fee plus a surcharge for each hour.
Now mind if you plan (i.e. are dumb enough) to pay the entire course up front, Ontario and BC do protect your advance payment if the school goes belly up.
In the real world, pay as you go works just fine.
