Canada Day in Ottawa will be filled with free activities and fireworks, but make sure to check ahead to see what's changing.

Environment and Climate Change Canada (ECCC) says it will be a hot and “soupy” day on Tuesday. Daytime temperatures will peak at around 27 C with a 70 per cent chance of thunderstorms and showers. At night, temperatures will hover around 17 C with a 30 per cent chance of showers, just in time for the fireworks.

Ottawa usually sees a “significant uptick in visitors” for Canada Day weekends, Mr. Miousse said. His organization has designed the Visit Ottawa Pass to complement the federal government’s Canada Strong Pass, which includes free or discounted admissions for children and youth to Canada’s national museums.
