A decorated police and army official, Sajjan has been the first Sikh to command a Canadian regiment -- called the Duke of Connaught's Own, which is a reserve regiment based in British Columbia province.
Sajjan has served in Afghanistan and Bosnia and been twice a special adviser on Afghanistan. He was given the Meritorious Service Medal in March 2013. A father of two, 45-year-old Sajjan was with the Vancouver Police Department for 11 years and served as a detective for the gang crime unit.
However, Sajjan's nomination as the Liberal Party candidate from Vancouver South last year attracted controversy when many Sikh leaders resigned from the Liberal Party, alleging that the party leadership has been 'manipulated' by hardliner Sikhs of the World Sikh Organisation. Sajjan's father Kundan Sajjan is a board member of the WSO which is alleged to have hardline sympathies.
But Sajjan told the Canadian Broadcasting Corporation last year: "I am not a member of the WSO. I've had no negative vibes from anybody." He was five when his father moved to Canada from Punjab. His wife Kuljit Kaur is a family doctor.
In the outgoing government, Tim Uppal was a turbaned Sikh but he enjoyed the rank of minister of state.
Herb Dhaliwal was the first Sikh to become a full cabinet minister in Canada in 1997, followed by Ujjal Dosanjh in 2004. Dhaliwal held the revenue portfolio while Dosanjh held the very important portfolio of health. Trudeau, the 42-year-old son of charismatic former prime minister Pierre Trudeau who is credited with opening Canada to new immigrants in the 1970s, led the Liberal Party to win 184 seats in the 338-member House of Commons. Trudeau is the second youngest prime minister of Canada.
