Lakeside Park is situated along the shore of Lake Ontario in downtown Oakville.  The park is the site of two historic buildings – The Old Post Office and the Thomas House – and is across the street from the Oakville Museum at Erchless Estate.

The park is open every day from 7am - 10pm, and the LOST Swim Group starts open water swims from this beach every Saturday morning at 8am from early June until late September.
