This is not a CEC Part 1 issue, it is a CEC Part II issue instead. The individual devices used to terminate connections, switched, receptacles, circuit breakers, etc. will be certified to a Part II standard.
If the device is certified to have two wires under one screw, as in some duplex receptacles and some circuit breakers, then it is acceptable to have more then one wire under a terminal fastener. If the device is not approved for multiple conductors under a single connection point, then it is not permitted.
