In a video, posted on his social media, Trudeau started with a Tamil greeting "Vanakkam!" before adding that "over the next few days, Tamils in Canada and around the world will gather with loved ones to celebrate Thai Pongal. Each day of this festival has its own special meaning and traditions which are tied to abundance, peace and happiness."
"On behalf of our family, Sophie and I wish everyone marking Thai Pongal a joyful harvest festival," he said.
"In 2016, the House of Commons voted unanimously to recognise every January as Tamil Heritage Month. I encourage everybody to reflect on the strong heritage of Canada's Tamil community. Our nation is stronger and richer because of Tamil-Canadians," Trudeau said.
"We should seize every opportunity to celebrate the many cultures, languages and beliefs that make our country such a wonderful place to live," he said.
