Very nice and informative video, thanks OP! I have no bitcoin ATMs around where I live so it's always nice to see that somewhere they exist.
In the past I encountered posts where people were complaining about high fees Bitcoin ATMs charge for the usage, but I don't think people would complain about this one. OP purchased 0.011 BTC for 20 CAD and then sold 0.01277 BTC for 20 CAD. We have less than 14% difference here between BUY and SELL, and I've heard about ATMs where such difference is over 20%.
