Tim Hortons said it will raise the prices of some items on its menu next Monday.
The company said there will be a "small price increase," but won't specify which items will cost more or by how much.
In February, Tim Hortons said it would pass along price increases for coffee and the ingredients for its doughnuts and other goodies to franchises and customers.
For that reason, prices at Tims outlets in the U.S. rose by three per cent almost two months ago.
Over the past year, the wholesale price of coffee has almost doubled.
It's partly because a fungus caused by rain and heat has killed much of the coffee crop in Colombia, one of the world's top three coffee-producing nations.
