National Donut Day is an annual tradition started in 1938 by The Salvation Army as a way to honour the men and women who served doughnuts to soldiers during WWI. Taking place the first Friday of June each year, this year's celebration takes place today.

Krispy Kreme is giving away a free donut at all locations, while the following Toronto indie donut shops are offering samples, in-store promotions, and special flavours.
