Trudeau said the two leaders had a brief conversation on the sidelines of the G20 summit in Antalya, Turkey, CBC News wrote.
"I pointed out that although Canada has shifted its approach on a broad range of multilateral and international issues, we remain committed to the fact that Russia's interference in Ukraine must cease; that we stand with the Ukrainian people and expect the president to engage fully in the Minsk peace process," he said.
Putin's relations with Western leaders have deteriorated over Russia's backing of pro-Moscow rebels in Ukraine. Trudeau's stand continues Canada's position under former prime minister Stephen Harper, a staunch supporter of Ukraine and one of Putin's most vocal critics.
During the election campaign, Trudeau called Putin a bully and accused him of being "dangerous" in eastern Europe, "irresponsible and harmful" in the Middle East and "unduly provocative" in the Arctic.
The Ukrainian Canadian Congress welcomed Trudeau's stand, calling it a "principled position" in response to Russian aggression.
"I look forward to working with Prime Minister Trudeau's government in ensuring that Ukraine remains a foreign policy priority for Canada; that the Canada-Ukraine Free Trade Agreement is ratified; and Canada supports the security and sovereignty of Ukraine," said national president Paul Grod in a statement to CBC News.
Grod urged the new Liberal government to take further steps, including "deep sectoral sanctions," against Russia for that aggression and for failing to meet obligations under the Minsk agreement.
"Anything less will embolden Russian President Putin to continue to breach international laws and borders, which may in turn jeopardize Canada's Arctic sovereignty. By helping protecting Ukraine, Canada will be protecting its Arctic sovereignty, and that is in Canada's national interest."
