Working across Seattle and Toronto means respecting a 3h difference. Your 9 AM in Seattle is 12:00 PM in Toronto, and Toronto's 5 PM is 2:00 PM in Seattle. Neither number is intuitive until you've been burned by it on a live call.

5h 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 270 usable minutes for synchronous collaboration. Pick one meeting slot and protect it fiercely — let async workflows cover everything else.

Recurring calendar invites for Seattle–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 3h gap — it's that the 5h overlap creates a false sense of availability. Both sides are reachable at the same time, so meetings proliferate. The most effective Seattle–Toronto teams treat their overlap window as a protected resource: one synchronized meeting per day maximum, async-first for everything else.

Daylight saving time: Both Seattle and Toronto switch clocks on the same dates (March 8 and November 1), so the 3h gap is constant year-round.
