Trudeau, the eldest son of former prime minister Pierre Elliott Trudeau, took to the stage before a crowd of over 1,000 supporters in Ottawa on Sunday night, with a message of unity and hope with an eye to the next election in 2015.
Before politics, Trudeau obtained a Bachelor of Education from the University of British Columbia, spent time in Whistler, and taught social studies and French at West Point Grey Academy and Sir Winston Churchill Secondary in Vancouver.
He has described himself as “a son of Quebec and a grandson of B.C.”
On Sunday, Liberals in B.C. said they believed Trudeau could change the party's fortunes in the province.
"I think Justin Trudeau knows the province. He knows B.C. He's lived in B.C., he's taught in B.C. He knows the issues," said Herb Dhaliwal, a former Liberal cabinet minister for Vancouver South.
"He'll want to make sure he has a strong caucus and will be out there recuriting good, strong candidates so he can have strong representation from British Columbia."
Craig Munroe, former president of the Liberal Party of B.C., agreed, saying Trudeau's leadership was drumming up excitement in the province.
"It's remarkable, the degree to which he's generating confidence in people that may not have considered running before," Munroe said.
"I think you'll find that there's a lot people who become quite interested in a party that ends up being led by Justin Trudeau."
