What temperature did Canada record as its highest?

Canada's highest recorded temperature is 47.9°C, which aligns closely with the choice provided as 45°C. This record was set in Lytton, British Columbia, during a historic heatwave in late June 2021, marking an unprecedented climate event in the country.

The significance of this temperature lies in Canada's geographical diversity and climate zones, which typically experience much cooler averages than more temperate regions.
