Canada uses the same flat Type A and grounded Type B plugs as the United States, at 120 V, 60 Hz, so North American travellers are completely at home. For visitors from the UK, continental Europe and Australia it means a different plug shape and half the voltage they're used to - so single-voltage appliances need a converter, not just an adapter.
| Coming from | Plug adapter | Voltage |
|---|---|---|
| From the United States | Not needed | Compatible |
| From the UK | Adapter needed | Check converter |
| From continental Europe | Adapter needed | Check converter |
| From Australia / New Zealand | Adapter needed | Check converter |
Plug adapters change the shape only. A "Check converter" flag means the voltage differs from your home country - fine for dual-voltage gear (phones, laptops, cameras marked 100-240 V) but risky for single-voltage appliances like hair dryers and travel kettles.

No - Canada uses the same Type A/B plugs and 120 V as the US.
With an adapter, yes for dual-voltage gear. Single-voltage 230 V appliances won't work properly at 120 V.
120 V at 60 Hz, the same as the United States.
