Toronto operates on Eastern Time (ET) — UTC−5 in winter (EST) and UTC−4 in summer (EDT). Canada observes Daylight Saving Time on the same schedule as the US, with clocks moving forward in March and back in November. Toronto is Canada's largest city and one of the busiest transatlantic scheduling corridors, sitting at the centre of North American finance, technology and media.

Toronto vs UK Time
| Season | UK Time | Toronto Time | Gap |
|---|---|---|---|
| Winter (GMT vs EST) | 12:00 PM | 7:00 AM | Toronto 5 hours behind |
| Summer (BST vs EDT) | 12:00 PM | 7:00 AM | Toronto 5 hours behind |
Unusually, the gap between Toronto and London stays at 5 hours year-round, because the US and Canada shift their clocks within a week or two of the UK. The US and Canada change clocks on the second Sunday in March and the first Sunday in November; the UK changes on the last Sunday in March and the last Sunday in October. That leaves a one-to-two-week window each spring and autumn where the gap briefly narrows to 4 hours or widens to 6 — worth checking if a meeting falls in one of those weeks.

The Transition-Week Trap
The US and Canada spring-forward on the second Sunday in March; the UK doesn't move until the last Sunday in March. For roughly two weeks each spring, Toronto is only 4 hours behind London instead of 5. The reverse happens each autumn: Canada falls back on the first Sunday in November, a week after the UK's last Sunday in October, briefly making the gap 6 hours. A recurring meeting booked around either date is the easiest way to end up an hour early or late without noticing.
Does Toronto observe daylight saving time?
Yes. Toronto follows the same Daylight Saving Time schedule as the rest of Canada and the US: clocks move forward one hour on the second Sunday in March (EST to EDT) and back one hour on the first Sunday in November (EDT to EST).
What is the time difference between Toronto and London?
Toronto is 5 hours behind London for most of the year, since Canada and the UK observe daylight saving on close but not identical schedules. For a one-to-two-week window each March and November — when one side has changed its clocks and the other hasn't — the gap briefly shifts to 4 or 6 hours.
What time should I schedule a call with Toronto from the UK?
Late morning to mid-afternoon UK time, roughly 1pm to 6pm, lines up with a normal working morning in Toronto. Outside the one-to-two-week transition windows each spring and autumn, that overlap holds steady at a 5-hour gap.

Toronto's near-constant 5-hour gap to the UK makes it one of the easier North American corridors to manage, except in those short transition weeks — exactly where scheduling across time zones usually goes wrong.
