Canadian here. You can try booking an appointment with a provider specializing in ADHD on Maple (it's a telemedicine app). First appointment is a screening/intake appointment, if they feel you're likely to have ADHD or rather you might be a better fit for something else (e.g. anxiety), they'll schedule a follow-up appointment for that. Prices are pretty transparent on their app, but IIRC it's in the realm of a few hundred CAD for both appointments.
