Joey Coleman, a volunteer with Open Hamilton, has prepared an online map of beaches, pools, waterparks, wading pools and splash pads in Hamilton.
You can browse the map for locations, or enter your address to zoom in on it and identify nearby cool spots.
With record-breaking temperatures in this week's heat wave, finding ways to cool off becomes a serious health issue.
The City of Hamilton has been at a stage 3 heat alert since July 19, due to high temperatures combined with a Humidex of over 40. High humidity makes it harder for the body to cool itself through perspiration.
On Thursday, July 21, the temperature in Hamilton reached 36° C (96.8° F) with a Humidex of 48.
