Northern Lights Festival Boréal

Northern Lights Festival Boréal is an annual summer music festival in Sudbury, Ontario. It is one of Canada's oldest continuous music festivals, having been staged every year since 1972 until the COVID-19 pandemic.

The bilingual festival is held on the shores of Ramsey Lake at Bell Park, home of the Grace Hartman Amphitheatre. A diverse program of music is presented in a variety of genres including arts, crafts and children's entertainment, featuring a mix of national, international and Northern Ontario artists and performers. Musicians at the festival typically participate in concert performances and workshop sessions, collaborating with several other musicians.

In addition to the main festival, the organizing committee also sponsors concerts and other cultural events in the city throughout the year.

The festival is normally held on the first weekend in July. Most commonly held over three days from Friday to Sunday, the festival at various times in its history has also taken place over one, two or four days.
