During EST (standard time), Toronto is 10.5h behind IST. During EDT (daylight saving), the difference becomes 9.5h. The live clock on this page always shows the correct current time.
When do clocks change in Toronto and how does it affect IST?

Toronto follows the same DST pattern as New York. During EDT (Mar–Nov) the IST gap shrinks from 10h 30m to 9h 30m. Indian diaspora in Brampton & Mississauga frequently coordinate calls with family in India.

What is the best time to schedule a meeting between Chennai and Toronto?
There is no overlapping standard business hours window. The best compromise is 5:30–7 PM IST, which corresponds to early morning in Toronto. For regular team syncs, consider 6 AM EST / early evening IST. Note: optimal windows shift by 1 hour when Toronto changes clocks — update your recurring calendar invite each spring and autumn.
Does India observe daylight saving time (DST)?
No. India (IST, UTC+5:30) does not observe daylight saving time and has not done so since 1945. Indian Standard Time is fixed year-round. This means that when Toronto changes its clocks in spring or autumn, the gap between Chennai and Toronto changes — but Chennai stays fixed.
Why is India on a half-hour timezone (UTC+5:30)?
India's UTC+5:30 offset was established in 1905 as a compromise between the time zones of Bombay (UTC+4:52) and Calcutta (UTC+5:54) when India unified under British rule. Several countries use half-hour or quarter-hour offsets — including Nepal (UTC+5:45), Iran (UTC+3:30), and parts of Australia (UTC+9:30) — to better align solar noon with clock noon across their territory.
