The humidex reading soared to 40, making it feel even warmer. Butchart Gardens closed its world-famous attraction on Sunday, school-bus pickups are being cancelled, the University of Victoria is closing its campus Monday, and B.C. Hydro reported unprecedented demand for power as a punishing heat wave continued to topple temperature records across Vancouver Island and the province. Lytton, on the Trans Canada Highway between Boston bar and Lilooet, smashed Canada’s all-time maximum temperature record Sunday afternoon after reaching 46.1 C. The highest previous record was 45 C set on July 5, 1937 around the towns of Midale and Yellowgrass in Saskatchewan, according to Environment Canada.
