Best Meeting Time: Toronto to Seattle
🕐 Live Timezone Overlap: Toronto & Seattle
Meetings between Toronto and Seattle hinge on a 6-hour window each working day. Toronto sits 3 hours behind Seattle at the time of writing, which puts the comfortable overlap at 12:00 PM to 6:00 PM Toronto time. Teams that work across these two cities tend to anchor their week-on-week sync into that block and push everything else to written updates. The widget below shows the exact mapping in both directions, including the small DST seasonal shift when one or both cities change clocks.
Time Difference: Toronto and Seattle
Seattle is currently 3 hours behind Toronto. The live offsets are Toronto UTC-4 and Seattle UTC-7. Toronto observes daylight saving and Seattle also observes daylight saving, so the offset shifts twice a year if both sides aren't already aligned.
Toronto observes daylight saving time, and Seattle also observes DST. When either side switches, the offset shifts by an hour. The US and Europe also change clocks on different weekends, so for one week in spring and one in autumn the usual offset between US and European cities is off by an hour. Always confirm with the live tool above when you're scheduling a recurring meeting that spans a DST changeover.
Best Times to Meet
Inside the 6-hour overlap, the best slots depend on local culture. Toronto tends to favour mid-morning meetings; Seattle works 9am–6pm as a default. Aim for the middle of the window where neither side is just starting or wrapping up. Avoid Friday afternoons if the other party has a strong end-of-week culture, and skip lunchtime in whichever city is in the 12–2pm block.

Tips for Scheduling Across Toronto and Seattle
- Aim for around 3:00 PM Toronto time: the middle of the overlap leaves room for both sides if the call runs long.
- Both cities observe DST, but the changeover dates may differ. Check the offset around late March and late October each year.
- Check USA's public holiday calendar in advance: a few national holidays shift entire working weeks.
- Canada Day (1 July) and Boxing Day (26 December) are statutory holidays not observed in the US.
- The gap is small enough that most teams keep one shared calendar in Toronto time and convert mentally.
Public Holidays and Working Weeks
Canada runs a Monday–Friday working week with Canada Day (07-01) and Thanksgiving (Canada) (second Monday in October) among the key closures. USA's major holidays include a standard public holiday set. Cross-check both calendars when scheduling recurring meetings: a 30-minute call in one city's holiday week typically gets a much lower attendance rate than the same slot a week later.
