Symbolism

The white oak is a canting reference to the town’s name, as well as a reference to forestry, its earliest industry. The water and the boat allude to the fact that Oakville was a shipbuilding hub on Lake Ontario well into the late 20th century. The boar heads likely allude to the badge of the Scottish clan Chisholm, therefore honouring William Chisholm, the founder of the town and harbour.

The blue and white mural crown was used for police burghs in Scotland and equivalent bodies elsewhere.
