Chicago and Toronto are 1h apart. When it's 9 AM in Chicago, it's already 10:00 AM in Toronto — meaning Toronto's working day is well underway before Chicago's morning has properly started.

The 7h 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 Chicago 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 1h gap — it's that the 7h overlap creates a false sense of availability. Both sides are reachable at the same time, so meetings proliferate. The most effective Chicago–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 Chicago and Toronto switch clocks on the same dates (March 8 and November 1), so the 1h gap is constant year-round.
