About the time in Ottawa
Ottawa sits at latitude 45.41, in the temperate-north band, so day length here swings sharply between midwinter and midsummer — today's 13h 50m is one point on that curve, not a fixed value.
Around 1,017,449 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.
If you are coordinating from another country, the shortcut is the working window: a normal Ottawa day of 09:00–17:00 falls between 13:00–21:00 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.
