Istanbul and Toronto are 7h apart. When it's 9 AM in Toronto, it's already 4:00 PM in Istanbul — meaning Istanbul's working day is well underway before Toronto's morning has properly started.
The 1h of overlapping business hours is your synchronous window. Use it for decisions, code reviews, and anything that genuinely requires two people to think together. Push everything else — status updates, documentation questions, non-blocking feedback — into async channels so you're not burning your shared window on things that could be an email.
For any recurring sync between Istanbul and Toronto, set the calendar invite in one canonical timezone and confirm the other side sees the correct local time. DST transitions can silently shift the effective meeting time by an hour for several weeks without either party noticing until someone is waiting alone on the call.
The bigger risk isn't the 7h gap — it's that the 1h overlap creates a false sense of availability. Both sides are reachable at the same time, so meetings proliferate. The most effective Istanbul–Toronto teams treat their overlap window as a protected resource: one synchronized meeting per day maximum, async-first for everything else.
Istanbul is UTC+3 and Toronto is UTC-4, a difference of 7h. This gap may shift by 1 hour during DST transitions.
The best meeting time is during the 1h of shared business hours — typically 4:00 PM to 5:00 PM GMT+3.
Yes, partially. Toronto observes daylight saving time; Istanbul does not. Toronto's clocks change around March 8 and November 1, shifting the gap between the two cities by 1 hour for part of the year.
Istanbul and Toronto share 1h of business-hours overlap (assuming 9 AM–5 PM local time for both).
