In early spring (typically peaking in March), when the daytime temperatures are above freezing and night temperatures are below freezing, consider visiting a sugarbush (or sugar shack) for fresh maple syrup, tours of orchards, and demonstrations of the maple syrup boiling process. Taffy on snow is a sugary treat made with freshly boiled maple syrup on fresh snow. There are many to choose from on farms in the countryside. Maple products are also sold at vendors in the Byward Market, and some bars will serve seasonal maple-infused craft beers from local breweries. Ontario's sugar shacks focus less on the culinary aspects of maple syrup than the Cabanes à Sucre found in Quebec, where you could expect a feast of hearty dishes alongside the season's syrup harvest.
