The federal government has declared Sept. 19 a National Day of Mourning for Queen Elizabeth II.
It's a holiday for the federal public service, but not an Ontario holiday, so provincial services are open and school is going ahead as scheduled.
Premier Doug Ford said Ontarians can participate in a moment of silence at 1 p.m. to honour the queen.
In Windsor, municipal offices are closed and the city is hosting a public viewing event for the queen's funeral at City Hall Square.
You can also watch live coverage from CBC News.
