This wikiHow guide will show you how to place a call to London from anywhere in Canada, using a cell phone, landline, or an international calling app.

Things You Should Know

Before dialing any international dialing code, you'll need to enter Canada's exit code, which is 011.
The country code for London and all of the United Kingdom is 44.
If you're dialing a landline, you'll need to preface the phone number with London's area code, which is 20 (e.g., 011-44-20-xxxx-xxxx).
