Simple answer is we would need everything. We lack all types of equipment, have next to no war stock, have very limited amounts of what we do possess, and do not have the capability to sustain ourselves for any extended length of time.
We would be facing a casualty rate of at least a company a day based off what is happening right now (likely more as since we would lack even the most basic defenses against certain equipment we would likely take higher casualties to that equipment). So that gives us what, two weeks? Three weeks? Basically the same amount of time it would take for our equipment to be completely destroyed.
The good news is that we don’t go to war without our big brother USA. And they happen to more than make up for our slack. If there was a real shooting war I can see us just asking to be fully equipped with whatever they are using as it would really be our only option to last any length of time. If we were on our own it would make the CAF look like the photo I attached of the Cameron's in WWI before and after, except that would more be what we look like after a couple weeks instead of years. Maybe give ourselves a place in history like the Polish Cavalry in WWII.
