Overnight lows near 20 C will “provide little relief from the heat,” the weather agency said.

It warned that the conditions could also bring deteriorating air quality.

Residents should take precautions due to an elevated risk of heat-related illness.

The Toronto area was also covered by a heat warning earlier this week.
