Defence Minister Bill Blair is defending Canada鈥檚 spending promise at the NATO leaders鈥� summit in Washington, D.C., as critics throw cold water on the government鈥檚 new pledge to meet the two per cent target by 2032.

鈥淭hat number didn鈥檛 sort of just come out of the air,鈥� Blair said Friday after returning to Toronto. 鈥淚t came out of a lot of hard work.鈥�

Prime Minister Justin Trudeau announced Canada鈥檚 new timeline Thursday, just hours before the end of the three-day summit and following days of pressure from NATO countries.

Members of the alliance have agreed to spend at least the equivalent of two per cent of national gross domestic product on defence. Canada was the only participant that arrived at the summit without a plan to reach the target.

While Trudeau鈥檚 commitment came with no details, Blair said Friday it amounts to about $60 billion a year starting in 2032, based on projections that Canada鈥檚 GDP will be a little bit north of $3 trillion that year.

Blair said the estimated projection came from NATO. It uses models from Organisation for Economic Co-operation and Development, of which Canada is also a member.

鈥淚t was important to be realistic about how long it was going to take to make these investments, to do it the right way,鈥� Blair said.

鈥淲e 鈥� thought the best and most verifiable date that we could provide to our allies was by 2032.鈥�

The announcement brought some assurances, with NATO Secretary-General Jens Stoltenberg noting in a news conference Thursday that it meant all allies now had a timeline.

British High Commissioner to Canada Susannah Goshko and U.S. Ambassador to Canada David Cohen both posted praise for the pledge on social media.

But there was also concern the promise could violate at least one of the federal government鈥檚 fiscal anchors.

Randall Bartlett, a senior director of Canadian economics with Desjardins, posted an analysis online that showed the plan could put at risk Ottawa鈥檚 need to maintain a declining deficit-to-GDP ratio for 2024-25, and to keep deficits below one per cent in 2026-27 and into the future.

He noted the federal government 鈥渃an raise revenues or reduce spending elsewhere to pay for the increased outlays on defence without increasing the size of the deficit.鈥�

Conservative Leader Pierre Poilievre criticized Trudeau鈥檚 performance at the summit, saying the prime minister was 鈥渢reated like a human pi帽ata by the rest of the NATO countries.鈥�

But as for the apparent reason Trudeau got that treatment, the Conservative leader said he would not commit to the alliance鈥檚 spending goal.

He said that鈥檚 because he doesn鈥檛 make promises he cannot keep.

鈥淓very time I make a financial commitment, I am going to make sure I have pulled out my calculator and done all the math,鈥� Poilievre said at a press conference in Montreal on Friday.

鈥淏ecause people are sick and tired of politicians just announcing that they are going to spend money without figuring out how they are going to pay for it.鈥�

Blair didn鈥檛 provide details or figures on how Ottawa will meet or pay for its promise, but pointed to 10 capabilities Canada wants to acquire that were in April鈥檚 updated defence policy.

They include shoring up ground-based air defence, modernizing artillery capabilities and acquiring a suite of surveillance and strike drones.

The biggest-ticket item, by far, is the renewal and expansion of the Canadian submarine fleet.

Trudeau and Blair announced this week that Canada is beginning the procurement process to buy up to 12 conventionally powered submarines that can operate under ice.

Blair would not say Friday what that could cost.

The lack of details attached to the new timeline brought skepticism among some business leaders and stakeholders over whether it鈥檚 realistic to expect the spending boost.

The Business Council of Canada鈥檚 CEO Goldy Hyder said the target year alone doesn鈥檛 鈥渃larify how any new defence investments will be fiscally sustainable.鈥� He added it is unlikely to quell concerns from international leaders.

Matthew Holmes, with the Canadian Chamber of Commerce, called the announcement 鈥渦nderwhelming at best.鈥�

In response to the criticism, Blair said the increased defence spending means the government has an opportunity to build better relationships with Canadian industry and workers.

鈥淚t鈥檚 not just a matter of spending money as quickly as possible,鈥� he said. 鈥淚t鈥檚 about investing.鈥�
