Do I need an adapter from the UK to Canada?
You need a Type B adapter for Canada.
United Kingdom: Type G, 230 V, 50 Hz → Canada: Type A/B, 120 V, 60 Hz.
Dual voltage (100–240 V input) covers 120 V. Type G plugs do not fit Canada's Type A/B sockets. Pack a Type B adapter.
Dual voltage (100–240 V input) covers 120 V. Type G plugs do not fit Canada's Type A/B sockets. Pack a Type B adapter.
Single-voltage device (230 V) on a 120 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 B plug adapter.
Some models are dual voltage and some are not. Check the INPUT line on the charger: 100–240 V works on 120 V with just a plug adapter; a single voltage needs a converter. Type G plugs do not fit Canada's Type A/B sockets. Pack a Type B adapter.

Single-voltage device (230 V) on a 120 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 B plug adapter. Canada runs at 60 Hz, not 50 Hz. Motors and clocks may run at the wrong speed; heating elements are unaffected.

Why
Plug shape. The UK uses Type G (three rectangular pins in a triangle, fused plug). Sockets in Canada are Type A (two flat parallel pins) and Type B (two flat parallel pins and a round earth pin). They are not compatible, so you need a plug adapter.
Voltage. The UK is 230 V; Canada is 120 V. Different voltage families. Dual-voltage devices (INPUT 100–240 V) are fine; single-voltage devices need a converter or will be damaged. Adapter or converter?
Frequency. The UK is 50 Hz; Canada is 60 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 the UK to Canada?
Yes. UK plugs are Type G and sockets in Canada are Types A or B, so you need a Type B adapter.
Do I need a voltage converter from the UK to Canada?
Only for single-voltage appliances. The UK is 230 V and Canada is 120 V, so an UK hair dryer, straightener or kettle needs a step-up converter (or a dual-voltage model). Phones, laptops and chargers marked INPUT 100–240 V just need the plug adapter.
Will my UK phone charger work in Canada?
Yes. Phone and laptop chargers are dual voltage (100–240 V). You only need a Type B plug adapter.
What about the reverse trip, Canada to the UK?
You need a Type G adapter for the United Kingdom, plus a voltage converter for your hair dryer or straightener. Full Canada to UK guide.
