Trudeau was joined at a ceremony at the Canadian National Vimy Memorial by French President Francois Hollande and by The Prince of Wales and his sons The Duke of Cambridge and Prince Harry.
"The Battle of Vimy Ridge was a turning point in the First World War and for Canada, when Canadians acted -- and fought -- as one," Trudeau said ahead of the commemorations.
"At Vimy Ridge, we will mark this great victory, and pay tribute to every Canadian who answered the call to serve."
The battle began early on April 9, 1917 and was part of a larger British-led offensive that included Australian soldiers, known as the Battle of Arras, which was a diversionary tactic to assist a major French attack further south.
It was the first time that four military divisions from Canada fought together as the Canadian Corps.
Canadian troops fought under Canadian command as a united force for the first time there, defeating the German forces in just three days, although they paid a heavy price with 3,600 Canadians killed and 7,000 wounded.
