Do I need an adapter from Canada to UK?
You need a Type G adapter for United Kingdom.
Canada: Type A/B, 120 V, 60 Hz → United Kingdom: Type G, 230 V, 50 Hz.
Dual voltage (100–240 V input) covers 230 V. Type A/B plugs do not fit United Kingdom's Type G sockets. Pack a Type G adapter.
Dual voltage (100–240 V input) covers 230 V. Type A/B plugs do not fit United Kingdom's Type G sockets. Pack a Type G adapter.
Single-voltage device (120 V) on a 230 V supply. A plug adapter alone will damage it; you need a voltage converter, or a dual-voltage model. You will also need a Type G plug adapter.
Single-voltage device (120 V) on a 230 V supply. A plug adapter alone will damage it; you need a voltage converter, or a dual-voltage model. You will also need a Type G plug adapter.

Single-voltage device (120 V) on a 230 V supply. A plug adapter alone will damage it; you need a voltage converter, or a dual-voltage model. You will also need a Type G plug adapter. United Kingdom runs at 50 Hz, not 60 Hz. Motors and clocks may run at the wrong speed; heating elements are unaffected.

Why
Plug shape. Canada uses Type A (two flat parallel pins) and Type B (two flat parallel pins and a round earth pin). United Kingdom sockets are Type G (three rectangular pins in a triangle, fused plug). They are not compatible, so you need a plug adapter.
Voltage. Canada is 120 V; United Kingdom is 230 V. Different voltage families. Dual-voltage devices (INPUT 100–240 V) are fine; single-voltage devices need a converter or will be damaged.
Frequency. Canada is 60 Hz; United Kingdom is 50 Hz. Chargers and heating elements do not care; motorised appliances and mains clocks may run at the wrong speed.
United Kingdom: The UK uses the fused three-rectangular-pin Type G plug (BS 1363) everywhere. The only exception is the shaver socket found in hotel bathrooms: a two-pin BS 4573 outlet, often switchable between 115 V and 230 V, limited to about 200 mA. It will run an electric shaver or toothbrush charger but nothing more powerful. Types D and M survive only for stage lighting and remotely switched lights.
Frequently asked questions
Do I need an adapter from Canada to UK?
Yes. Canada plugs are Type A/B and United Kingdom sockets are Type G, so you need a Type G adapter.
Do I need a voltage converter from Canada to UK?
Only for single-voltage appliances. Canada is 120 V and United Kingdom is 230 V, so a Canada hair dryer, straightener or kettle needs a converter (or a dual-voltage model). Phones, laptops and chargers marked INPUT 100–240 V just need the plug adapter.
Will my Canada phone charger work in UK?
Yes. Phone and laptop chargers are dual voltage (100–240 V). You only need a Type G plug adapter.
