The Société des Fils de la Liberté (French: [sɔsjete dɛ fis də la libɛʁte], Society of the Sons of Liberty) was a paramilitary organization founded in August 1837 in Lower Canada (now Quebec).
The society was founded by young supporters of the Parti patriote who became impatient with the pace of progress of the movement for constitutional and parliamentary reforms.
The Société des Fils de la Liberté held its first public assembly on September 5 and began to recruit men to form militias.
Various organizations had already been formed and pressured Governor Lord Gosford to act and quell the upcoming rebellion before lives were lost and property destroyed.
Following the November 16 order to arrest 26 Patriote leaders on charges of sedition, including Papineau, O'Callaghan, Brown, and Ouimet, many members of the Société des Fils de la Liberté took part in the armed conflict of 1837 and in both invasion attempts of 1838.
