London & Toronto Time Difference
🕐 Live Timezone Overlap: London & Toronto
London and Toronto sit five hours apart, with Toronto behind. That gap shapes every meeting request: when London teams are wrapping up at 5pm, Toronto colleagues are midway through their morning. The usable overlap is four hours, running from 2pm to 6pm London time and 9am to 1pm Toronto time. Getting that window right matters, because it is the only period when both cities are simultaneously within a standard 9am–6pm working day.
Time Difference: London and Toronto
Toronto is currently 5 hours behind London. The live offsets are London UTC+1 and Toronto UTC-4. London observes daylight saving and Toronto also observes daylight saving, so the offset shifts twice a year if both sides aren't already aligned.
London currently runs at UTC+1 (British Summer Time), while Toronto is at UTC-4 (Eastern Daylight Time), giving a current gap of five hours. Both cities observe DST, so the offset stays at five hours for most of the year. The catch is autumn: UK clocks change one week earlier than North American clocks, briefly creating a six-hour gap between London and Toronto for that one week until Canada catches up.
Best Times to Meet
The overlap runs four hours: 2pm–6pm in London and 9am–1pm in Toronto. Inside that four-hour window, the cleanest slot is typically 2pm–4pm London time (9am–11am Toronto). London's lunch runs 12:30–1:30pm, so callers are settled by 2pm. Toronto's Bay Street culture, where some teams are in by 8am, means early-morning Toronto calls are workable for finance teams, but 9am–11am suits most offices. Fridays in London often wind down by 4pm, so avoid late Friday slots.

Tips for Scheduling Across London and Toronto
- Book London-to-Toronto calls between 2pm and 4pm London time to catch Toronto's freshest morning hours.
- In the autumn changeover week, UK clocks shift first: add one extra hour to your usual London-Toronto gap for up to seven days.
- Avoid scheduling across London's 12:30–1:30pm lunch window; Toronto participants will be left waiting.
- Canada Day (1 July) is a Toronto statutory holiday with no UK equivalent; block it out separately on shared calendars.
- London finance teams sometimes run informal meetings between 5pm and 6pm, which maps to noon in Toronto and can work as a backup slot.
Public Holidays and Working Weeks
Both cities follow a Monday-to-Friday working week, with hours of 9am–6pm as the standard frame. Cross-city scheduling must account for separate public holiday calendars. London's next major holidays include the May Bank Holiday and Christmas Day; Toronto observes Canada Day on 1 July and Boxing Day on 26 December, neither of which is a UK public holiday. Always check both calendars before sending a recurring invite.
