Heat warnings in effect for parts of the country on Canada Day weekend
Heat warnings are in effect for much of Ontario and parts of Quebec heading into the long weekend, while the Maritimes are being cautioned about warmth and humidity.
Environment Canada has issued heat warnings for parts of northern Ontario and all of the southern part of the province.
The warnings stretch from Sudbury and North Bay down to Windsor and east past Montreal.
The national forecaster says temperatures could reach the mid-30s with humidex values into the mid-40s, while some areas could see severe thunderstorms.
Meantime, the weather agency has issued special weather statements for the eastern reaches of Quebec, as well as New Brunswick, Nova Scotia and Prince Edward Island.
It says ``a very warm and humid airmass'' will settle over eastern Quebec and the Maritime provinces this weekend, and will last into next week.
