Environment Canada has lifted the heat warning it issued late last week for the national capital region, bringing an end to a "multi-day heat event" that brought temperatures in the low-to-mid 30s to Ottawa-Gatineau.

The weather agency issued warnings Saturday afternoon for the area, as well as a large swath of eastern Ontario stretching from Prince Edward County north to Pembroke and east to Cornwall and the Quebec border. 

In Ottawa, daytime highs were in the 30s, but with humidity factored in it sometimes felt hotter.

An earlier heat wave in late June saw similarly brutal temperatures across the region, with communities like Ottawa, Gatineau, Kemptville and Trenton all setting daily records, according to preliminary Environment Canada data.

CBC’s Nkele Martin spoke with experts about dangerous symptoms to look out for and what types of activities are safe when the mercury starts to rise.

Health Canada recommends staying cool and staying hydrated when extreme heat hits.

That can mean everything from drinking lots of water and rescheduling outdoor activities for cooler times, to preparing meals that don't require ovens and keeping track of nearby air-conditioned spaces.

Watch for signs of heat exhaustion — like a headache, dizziness or a rapid heartbeat — and get to a cool place where you can drink water.

Heat stroke, which includes symptoms like confusion and very hot or red skin, is a medical emergency. Anyone who feels they have heat stroke should call 911.
