The custom of celebrating from the end of January until mid-February has long been popular in Quebec City, Canada. The first large Winter Carnival here, in the world’s snow capital, took place in 1894. Faced with winter’s hardships, the city’s population made this popular tradition into a winter celebration that warmed the hearts of all people.

Interrupted by two wars and then the economic crisis of 1929, the Carnival was held from time to time until the second half of the century. In 1954, a group of business people re-started the festivities. That year, Bonhomme was born and was elected the event’s representative.

The next year the first official Quebec Winter Carnival took place. The Carnival snowballed into a big event and was important for tourism and economic activity in the city.

From one winter to the next, the Carnival enriched its activity program. We have since added even more popular activities, such as winter sports, snow sculptures, and activities based on the traditional Quebec lifestyle, such as dogsled races. The Quebec Winter Carnival is the largest winter carnival in the world today, and is third on the list of Top Carnivals after the famous carnivals in Rio and New Orleans.
