I am a law student at the University of Ottawa but I'm from Durham Region (near Oshawa). My father is David Garant from Timmins, son of Gaston Garant from Timmins, son of Joseph Garant from the Gaspé.
Hopefully this was helpful, let me know if you have any questions.
I know my aunt, Brenda Garant, did some research and found that the first Garant to land in Quebec was Pierre Garant in the 17th Century... I think 1648?
