Ottawa: Canadian Prime Minister Justin Trudeau celebrated the Hindu festival of lights Diwali with the Indian community in Ottawa on Monday.

Attired in a black Sherwani, Trudeau lit the ceremonial lamp and wished the Indian Diaspora a happy Diwali.

Indian High Commissioner to Canada Vikas Swarup was also present on the occasion.

“Diwali Mubarak! We’re celebrating in Ottawa tonight. #HappyDiwali!,” Trudeau tweeted.

The light-hearted gesture by the Canadian PM got twitterati trolling him for using the word ‘mubarak’ instead of ‘shubh’ or ‘Happy’. What followed was a thread of tweets from people arguing about the origin of words like ‘Hindu’ and ‘Mubarak’ and whether they are Arabic or Urdu.
