Environment Canada has lifted its heat warnings for Ottawa and the surrounding area.
The nation's capital was placed under a heat warning on the weekend, and daytime temperatures have hovered around the 30 C range for six straight days.
However, temperatures are expected to cool off tonight, with the weather agency forecasting an overnight low in the mid-teens.
Highs are expected to settle in the mid-20s over the next few days, with a chance of rain on the weekend.
An open-air fire ban in Ottawa remains in effect.
