Personnel is difficult to increase quickly if the way to achieve that is more Canadian Forces personnel. An easy way to increase spending on personnel is to increase the salaries and wages paid to CF personnel, which I'm sure they wouldn't say no to. It would increase the spending, but it wouldn't necessarily increase the capacities of the Canadian Forces.
With equipment, there are constraints related to supply. When it comes to operations, they're constrained by the equipment and the personnel.
One easy way would be to significantly increase veterans' benefits but, again, that would be an increase in spending. I'm not sure it would necessarily be related to a commensurate increase in military capabilities or readiness.
