Activities for Canada Day in Ottawa have been suspended until further notice due to weather, as flooding closed some streets in the city and thunderstorms led to power outages.
As heavy rain fell across the capital, the Canadian Heritage department posted online that activites at LeBreton Flats Park, Old Hull, Parliament Hill and in front of the Supreme Court of Canada have been paused as of 2:40 p.m. on Wednesday.
“Due to weather conditions, the activities offered at all sites in Canada’s Capital Region are suspended until further notice,” Canadian Heritage wrote, advising people to check back for updates.
At LeBreton Flats Park and Parliament Hill, electronic billboards advised attendees to seek shelter. As heavy rain and winds lashed the area, people ran to vacate the park, video posted online showed.

Around 4:30 p.m., the Canadian Forces Snowbirds posted online that they would not be able to fly over Parliament Hill as planned.
“But we’re not giving up!” they wrote.
“We’ll be watching the skies closely and will attempt to get airborne between storm fronts to overfly the National Capital Region. We can’t provide specific times, but you can track us in real time — follow SNBD1 on your favourite flight tracking app to see when we’re in the air.”
