Why people convert Toronto to GST time

Scheduling a call from Toronto to GST: a 10:00 AM start in Toronto lands at 6:00 PM in GST, so you can confirm the slot without doing the arithmetic yourself.
Handling a +8h gap: Toronto and GST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in GST is 5:00 PM in Toronto.
Coordinating a Toronto-based team with GST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM EDT" is unambiguous; "3 PM" across a +8h gap is not.
With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week Toronto takes the early slot, the next week GST does.
Toronto: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +8h gap.
