Can someone tell me if the Canadian electrical code requires an ground

the box, but a fellow electrician just told me they now need to be

What would be the advantage to grounding a switch? I see none.



I think grounding of switches appeared in the US-NEC to provide a ground
for metal plates. Switches have to be grounded by:
1 - attachment with metal screws to a metal box (or plastic box with
integral grounding means).
2 - ground wire attachment to a grounding screw on the switch (used for
plastic boxes).
(there are exceptions)
