Time difference between Perth and Toronto

Toronto is 12 hours behind Perth

Perth, Australia is UTC+8 · Toronto, Canada is UTC−5 — on standard time

The gap is not the same all year

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Perth does not change its clocks and Toronto goes forward on the second Sunday in March and back on the first Sunday in November.

Perth stays put all year while Toronto moves, so the gap changes twice a year from Toronto's side alone. A recurring meeting set in Perth's calendar will drift by an hour without anyone touching it.

When they can both be at their desks

Nine-to-five in Perth and nine-to-five in Toronto do not overlap at all. With 12 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
