Best time to call Toronto from London (and vice versa)

The window in which both cities are inside their 9:00–17:00 working day runs from 14:00 to 17:00 in London, which is 09:00 to 12:00 in Toronto: 3 hours of overlap per day. For a call that disturbs nobody, aim for the middle of that window.

Outside that window, the practical rule: mornings in London are afternoons in Toronto. Avoid any hour that falls before 8:00 or after 21:00 in either city.
