A blistering heat wave struck much of the country this weekend, keeping in line with predictions Canadians would see above-normal temperatures this summer. The mercury rose in Ontario, Manitoba and Saskatchewan, but the Atlantic provinces and British Columbia were left in the relative cold. Officials issued a heat and humidity warning in Montreal after temperatures hit 32 C on Sunday, while Environment Canada recorded a record-breaking high of 34.6 C at Pearson International Airport on Sunday afternoon. Manitoba and Saskatchewan are both expected to see highs in the 30s this week.
