This has long been the problem with NATO requirements - the US has expected the money to funnel to them. If anything, Canada's NATO money should be spent in Canada. Isn't the US way behind in their contributions to the UN?
Plus NATO wouldn't need as much spending if the US wasn't continually instigating wars around the world to appease their oligarchs. Has there been a war anywhere in the world in the last 80 years that didn't have CIA fingerprints all over it?
