Fine, I negate my earlier response but alas! We sucked even back then yes, but the DAY we declared war, almost 50,000 Canadians volunteered to join the army! That's about everything we have in our entire armed forced right now. That I find impressive. Although I am shocked at the figures you produced above.
I'll attempt to find the link where I read that, it was few months back.
Don't mistake absolute numbers for Army quality. The Canadian Army in 1939 was a sad, hastily constructed force suffering from years of neglect (as Mr O'Leary has pointed out) and McNaughton's bizarre peacetime experiments. As well, professionalism was spotty and the Army was not at all prepared to execute operational level combat. Read English's The Canadian Army in Normandy for a good analysis of the Army in the 30's and 40's.
As well, the "sucked even back then" part sounds like you're talking out of your lane again. Today, despite resource and manning issues, we have a very professional force serviced by leadership (Officers, WO, and NCO's) who have a great deal of real world operational experience (at least this is what our Allies consistently say). Despite lacking in some key equipment departments, the rest of it is usually top-notch. You're in the Militia and you are equipped exactly like your Reg Force brethren (service rifle, equipment, etc) - do you know how uncommon that is? I've seen our Army (both Reg and Res) next to the soldiers of other countries; don't be so keen to discredit your fellow soldiers and your Army.
As for the original topic, past Canadian battles, I've been reading a bit about the War of 1812 in the last little while - a battle history of Chateauguay in a past issue of the ADTB and a battle history of Queenstown in Fighting For Canada. What really grabs my interest is the primary source material that recounts the ferocity and feared combat abilities of the Natives of North America. Their way of fighting, based off of "the hunt" (stalking, infiltration, marksmanship, etc) was truly asymmetric and could be used to great effect at times - witness Norton's roundabout assault with a handful of Native warriors at Queenstown.
