A video uploaded on Tuesday shows the Liberal party leader, donning a desi white kurta-pyjama, dancing to the catchy beats of Hadippa - the breakout theme song from the 2009 Bollywood film "Dil Bole Hadippa!", the Huffington Post Canada reported.
According to a party spokesperson, the footage was captured during an event organised by the India-Canada Association of Montreal in 2009.
For some, the footage reminds viewers of Trudeau's father Pierre Elliott Trudeau and his signature prime ministerial pirouette.
Pierre Elliott Trudeau served a total of four terms in the country's top office. Justin is his eldest son.
More recently, Harper's wife Laureen showed off her own bhangra dance moves at a Conservative campaign event in Brampton, Ontario last week.
The old bhangra video and Trudeau's youthfulness are attracting renewed interest in Canada after voters elected a majority Liberal government on Monday, unseating former prime minister Stephen Harper's Conservative party from nearly a decade in power.
The Indian-Canadians more than doubled their representation in the Canadian parliament from eight to 19, as Canadians voted out the Conservative Party in a landslide of 184 seats in the 338-member House to the Liberal Party.
For a record, among the winners are five Sikh women and five turban-sporting Sikhs.
