Voltage & Electricity
Canadian appliances operate on 110 volts (60Hz), which is identical to the US voltage. A universal adaptor is required for overseas electrical devices.
Main wall sockets (or power outlets) and plugs for 110 volts are two parallel flat blades. If those sockets are different from the ones used in your country you will need a socket converter.
