Environment Canada lists no active Ontario weather alerts at 12:21 a.m. EST Saturday.
Heading into the NetNewsLedger Newsroom this morning, there is frost on the lawn, and light gloves are needed for that early morning walk.

Wardrobe

Weather trivia
Lake Superior slows temperature changes near its shoreline because water warms and cools more slowly than land. Inland locations such as Kakabeka Falls can therefore have colder nights even when daytime highs are similar.
