I live in New Zealand, similar health system to Canada. I broke my pinky finger a few months ago, late-ish on a Saturday night - busy time for the drunks and so forth attending the emergency department. 45 minutes in and out, x-ray'd, splinted and with follow up appointment booked. A few weeks later I started seeing a hand therapist to make sure all the mobility came back, total of 6 visits.
