Prime Minister Justin Trudeau is heading to the capital Washington next week to participate in the NATO leaders' summit.

The 32 NATO member countries are scheduled to celebrate the 75th anniversary of the founding of the alliance in the same city where the initial treaty was signed.

The ongoing war in Ukraine is expected to once again take center stage this year.

NATO Secretary General Jens Stoltenberg wants allies to contribute about $58 billion annually to a fund to help the war-torn country defend itself.

Trudeau is also likely to face pressure from allies, including the American unit, due to the fact that Canada has not presented a plan to achieve its spending targets.

NATO countries have agreed to spend at least 2% of their annual GDP on defense, but Canada remains far below this figure.
