Canada uses the same AWG sizes and 120/240 V split-phase service as the US — but the Canadian Electrical Code makes the limits mandatory: Rule 8-102 caps drop at 3% for a feeder or branch circuit and 5% from supply to point of utilization. Same math as the NEC, none of the 'informational note' ambiguity.
Physics and conductor data are identical — Table 8-style resistance, AWG, the ×2 round trip. The legal status flips: under CEC 8-102 an inspector can fail an installation on voltage drop alone, so Canadian work designs to 3%/5% as hard ceilings, with calculated demand current as the basis. Cold climate adds a practical wrinkle: long runs to detached garages and block-heater circuits are routine, and the EV charger and garage feeder presets apply unchanged.
Yes — CEC Rule 8-102 is a requirement, not a note. 3% maximum for a feeder or branch circuit, 5% total from supply service box to the point of utilization.
The conductor resistance and ampacity tables are effectively common; verify ampacity details against CEC Table 2 for your installation condition, and treat every drop result here against the mandatory 3%/5%.
