The Canadian International Air Show could not go ahead as planned on Saturday in Toronto because choppy waters on Lake Ontario would have impeded emergency boats.
Winds gusted at 60 to 80 km/h in southern Ontario during the day, but eased in the evening, and were expected to further die down overnight. That's good news for the air show, which is expected to give Sunday a try.
“It was all due to the passage of a cold front,” says Greg Stephens,” a meteorologist at The Weather Network. The cold front also dragged down temperatures to the teens -- a dramatic change from the high 30's seen earlier in the week.
The air show has marks the final days of the Canadian National Exhibition, the late summer tradition in Toronto. The last day of The Ex is on Monday, which is Labour Day.
Visitors to the fairground on the edge of Lake Ontario were already wearing fall gear on Saturday and carrying umbrellas to take cover from lake-effect showers.
Drier air arrives on Sunday, but there will be a risk of scattered isolated showers.
While it may have felt like the end of summer, and The Ex's is considered an “end of summer” festival, Stephens reminds us that it isn't over quite yet.
“We could have some hot days in Southern Ontario. It's only early September. Summer is officially over September 21,” he says.
