I'll disagree with you on this one though. While I think that air and sea should be the priority you can't ignore the land. Ultimately you can't control territory without "boots on the ground". For that you need conventional land forces.
Where
@KevinB and I disagree is over how many of what type of forces are appropriate for Canada. I argue for a Brigade Group minimum (plus additional enablers) as anything smaller than that is not only politically insignificant but also really impossible to operate with any degree of autonomy in a major conflict. You'd be putting our troops under someone else's direct command. [realistically ANY sized force Canada deploys in a major war will ultimately under US/Allied command, but anything smaller than a Brigade would have to be under direct tactical command]
Others argue that based on the size of Canada we should be able to deploy at least a Division. Anything less isn't enough to show our Allies we are really taking on our share of the burden in the fight by putting our own sons & daughters lives on the line beside our partners.
I disagree with that in so far as I think that our sailors and aircrews will equally be in the line of fire doing the vital task of preventing our enemies from disrupting the flow of troops and equipment from the USA to the conflict zone. Every American ship or aircraft that we ensure arrives safely will have profoundly more impact on the conflict than additional Canadian boots on the ground in my opinion so I'll gladly trade the two extra Brigades required to deploy a full Division for additional RCN and RCAF assets.
I'd also suggest that if we are to deploy anything beyond a Brigade Group it would be more impactful (based on observations of recent conflicts including Ukraine) to deploy additional units such as artillery, long range precision fires, air defence, ISR, EW, etc. over more infantry/armour. It may be less people deployed overall...and less perhaps directly on the front lines, but I think it would likely be more impactful militarily.
