"Diwali Mubarak!" wrote the Canadian politician in photos posted on Twitter and Facebook. "We're celebrating in Ottawa tonight. #HappyDiwali!"
Mr Trudeau, photographed wearing a black sherwani, was immediately corrected by some on social media:
It's not "Diwali Mubarak", it's "Diwali Ki Badhai" ... Correct it ..— Bhavesh K Pandey (@bhaveshkpandey) October 17, 2017
Word to the wise : It's "Shubh-Deepavali", (Auspicious Deepavali), and NOT "Diwali Mubarak". "Mubarak" is Arabic, not Indian. @CanadainIndia— Truthsayer (@a_truthsayer) October 17, 2017
PM Justin, thanks for the Deepavali Greetings. Confirm w. @CanadainIndia, please amend your tweet. Nobody, but nobody, says "Diwali Mubarak"— Truthsayer (@a_truthsayer) October 17, 2017
Thank you, Mr.PM. Its good to hear from a global icon. But it's either 'subh deewali' (Hindhi) or deepavali Vazhthukal(Tamil).— Abinayah Raguraam (@AbinayahR) October 17, 2017
Others were quick to dismiss what they saw as unnecessary criticism:
You are awesome. Not sure why ppl getting offended by "Mubarak" Respect the sentiments behind, Mubarak just an Arabic word for blessing— Shaan (@Shanyousaf6) October 17, 2017
Mubarak is Urdu word and badhai is Hindi/Punjabi , they both mean the same. Give some cushion to a westerner ffs.— Eye of tiger (@Aqal_k_dushman) October 17, 2017
Most, however, appreciated the Canadian politician's gesture and returned the greeting:

Here are some more pictures from the Diwali celebrations in Ottawa:
Diwali, or Deepavali, is the Hindu festival that celebrates the victory of good over evil. Also known as the Festival of Lights, Diwali is traditionally celebrated by lighting diyas and candles, praying to Goddess Lakshmi and Lord Ganesh and meeting family and friends to exchange Diwali greetings and gifts. The festival of Diwali will be celebrated on October 19 this year.
The Canadian PM routinely takes to social media to celebrate different cultures and faiths.
He has been spotted at least twice before in kurtas as well. Click for more trending news
