Prime Minister Justin Trudeau is heading to Washington next week to take part in the NATO leaders' summit.
The 32 NATO allies are set to mark the alliance's 75th anniversary in the same city where the initial treaty was signed.
The ongoing war in Ukraine is expected to take centre stage again this year.
NATO Secretary-General Jens Stoltenberg wants allies to contribute around $58 billion a year to a fund to help the war-torn country defend itself.
Trudeau will also likely face pressure from allies, including the American contingent, over the fact that Canada hasn't presented a plan to meet its spending targets.
NATO countries have agreed to spend at least two per cent of their annual gross domestic product on defence, but Canada is falling far short of that figure.
