Trudeau was accompanied by Deputy Prime Minister Chrystia Freeland, Foreign Affairs Minister Mélanie Joly and an armed security detachment.
Trudeau also announced more military assistance for Ukraine would be given including drone cameras, satellite imagery, small arms, ammunition and funding for de-mining operations.
The Canadian prime minister also announced Canada will be removing trade tariffs on all Ukrainian imports coming to Canada for the next year.
Trudeau visited the city of Irpin, on the outskirts of Kyiv, which was the scene of some of the heaviest fighting in March as Russian forces attempted to take the capital.
Trudeau is the latest of world leaders, dignitaries and celebrities who've visited Ukraine to show their support. Rock musicians Bono and The Edge of U2 gave a surprise concert at a Kyiv subway station several blocks from the presidential palace on Sunday.
