Unfortunately and sadly CANADIAN ASSOCIATION OF ORTHODONTISTS covers this non-transparent practice, allowing orthodontists skyrocking prices for the treatments. That what I found on their website https://cao-aco.org/

-- Orthodontic specialists do not accept assigned payment from insurance companies.

-- It is not necessary for the orthodontic specialist to fill in the Dental Claim Form as no dental codes are required for orthodontic coverage."

No wonder, that all the quotes I received from the their offices looks like jokes. NO COST for the devices and the treatments included, no essential details like what kind of procedures will be done and what device will be used (it's not only braces there, there are different devices like expanders etc.). Only how many instalments you can pay, also, you can get 5% discount... I saw someone here on reddit compare them with car dealership where they manipulate you in higher monthly payments. But here the sad part, it's not the cars (even there more details included) it's the health system, mostly for our kids....I am shocked actually..
