About the time in Ottawa
If you are coordinating from another country, the shortcut is the working window: a normal Ottawa day of 09:00–17:00 falls between 14:00–22:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
Around 18,768 people live in Ottawa, and all of them keep the same civil time, so the reading above applies to the whole urban area — not just the city centre.
Ottawa sits at latitude 41.35, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 31m is one point on that curve, not a fixed value.
