Today is Dairy Queen's 17th annual Miracle Treat Day.
Participating D-Q's in Niagara, Hamilton, Brantford, Burlington, Caledonia and Simcoe will donate net proceeds from every Blizzard Treat to McMaster Children's Hospital.
Mac is one of 12 children's hospitals across the country supported by the Children's Miracle Network.
Since the partnership began between the DQ and the charity in 1984, the ice cream chain has donated more than $39 million to the 12 hospitals.
