The cubs are the first giant pandas to be born in Canada.
Trudeau helped reveal their names -- Jia Panpan and Jia Yueyue -- which mean "Canadian hope" and "Canadian joy," respectively, the Toronto Zoo tweeted. Members of the public voted on the names from a list of seven different pairs.
Trudeau even got a chance to snuggle with the cubs, reportedly joking that his children would be jealous.
Monday also marked the pandas' first public appearance since their birth. Visitors to the zoo will have the opportunity to see the cubs this weekend, according to the Toronto Star.
The pandas' mother, Er Shun, is on loan from China and has been at the Toronto Zoo since 2013, the CBC reported. She and a male panda, Da Mao, will be at the zoo until spring 2018, according to the zoo's website.
