Preparing for a hypothetical war in Canada involving the invasion of the Country by a foreign military power wouldn't be able to rely on conventional military power to defend itself.
It would need to be fought by guerilla forces and partisans.
In a hypothetical situation where the United States was that foreign military power, the CAF would be of negligible utility. The CAF is in bed with the US MIC and the leadership is too close to the US Military. The same could be said for most of our Govt as well.
An organization structutred like the Canadian Defence League:

It would need to be ultra-nationalist in nature and maintain an arms length distance from the Government with the only connections being to the intelligence services.
