Socket (hexagon) and Robinson (square) are hyper common standards. You use Robinson for wood working due to the shape offering more resistance for high speed driving, and you use a socket with an allen key in order to get precise high torque hand tightening. IMO Phillips and Slot are the worst common standards due to stripping and sliding.
I'm not Canadian myself, but I did know that. Other than some cheaper ones being a bit weak from the large-ish chunk required for the square-drive, they're really great. Much more pleasant to use than Phillips.
