Working across London and Toronto means respecting a 5h difference. Your 9 AM in London is 4:00 AM in Toronto, and Toronto's 5 PM is 10:00 PM in London. Neither number is intuitive until you've been burned by it on a live call.
3h of shared working time sounds like plenty until you factor in lunch breaks, context-switching, and the inevitable late start. In practice you have closer to 150 usable minutes for synchronous collaboration. Pick one meeting slot and protect it fiercely; let async workflows cover everything else.
Recurring calendar invites for London–Toronto meetings need a DST audit every year. If one city's clocks change before the other's, there's a window (sometimes three weeks, sometimes five) where the same calendar slot lands an hour earlier or later than intended. Always schedule with explicit timezone labels, not just clock times.
The bigger risk isn't the 5h gap; it's that the 3h overlap creates a false sense of availability. Both sides are reachable at the same time, so meetings proliferate. The most effective London–Toronto teams treat their overlap window as a protected resource: one synchronized meeting per day maximum, async-first for everything else.
London is UTC+1 and Toronto is UTC-4, a difference of 5h. This gap may shift by 1 hour during DST transitions.
The best meeting time is during the 3h of shared business hours, typically 2:00 PM to 5:00 PM GMT+1.
Yes. Both cities observe daylight saving time, but on different schedules. Toronto springs forward on March 8 and London on March 29, so the gap between them shifts by 1 hour during the spring and fall mismatch window.
London and Toronto share 3h of business-hours overlap (assuming 9 AM–5 PM local time for both).
