Time Difference Between Sydney and Toronto

Sydney is 14 hours ahead of Toronto. Sydney runs on Australia/Sydney (UTC+10); Toronto runs on America/Toronto (UTC-4). The difference is measured right now; it can shift by one hour during daylight-saving-time transitions.

Both Sydney and Toronto observe daylight saving time, but their transition dates are not identical. Sydney shifts between AEST (UTC+10) and AEDT (UTC+11); Toronto shifts between EST (UTC-5) and EDT (UTC-4). The difference between them stays close to 15 hours across most of the year, with short mismatch windows around each city’s transition when the gap briefly widens or narrows by an hour.

Standard 9-to-5 business hours in Sydney and Toronto do not overlap. Teams operating across this pair either stretch their schedules — an early-morning call from the westward city lands as an evening call in the eastward one — or rely fully on asynchronous tools. Scheduled windows at the edges (first thing for one side, last thing for the other) are the usual compromise, with one side absorbing the unsocial-hours cost this week and the other side next week.

When planning recurring meetings across Sydney and Toronto, pin them to one city’s local time rather than UTC or the other city’s clock. That way, the meeting time stays stable for the person anchoring the schedule, and the other side absorbs the one-hour drift during DST transitions. The alternative — a meeting pinned to the non-DST city — means the DST city sees the meeting time “move” twice a year, which is how recurring calendar invites end up at 7am on someone’s calendar in October.
