Canada and canadians do not like to think of themselves as a "war-like" people. We do not like to consider the need for a military to be anything more than peace-keeping - we have the US for homeland defence afterall.
Example: Recent Presidential elections, the military backgrounds of the candidates were front and centre. A deeply patriotic (and military sensitive) people, the Americans support their army to the ends of the earth... and as they should. Without getting into US economic dependency on military force projection, and defence spending, Americans grow up fostering a deep sense of their own history (however fragmented and distorted it may be taught) and thus have a great reverence for their place in the world, and the need for their military to sustain it.
Canada is different. We all come from different places, much of our pop is provided for by immigration. We have become a place for acceptance, and our culture is generally one of open arms (from social programs to immigration to refugees to stranded air passengers, to strippergate, we accept em all). As a result, while many Canadians love our place in the world, many don't feel the need to pronounce it. Because we dont do this, and we did not have a violent independence movement from Britain (at least as compared to the US) we have never fostered the need for a strong military presence to establish ourselves in the world. As a matter of fact, much of this was left up to Britain fairly far into the early 1900s. We have always depended on someone else to do the work for us on hte regular term... and we only come running when the situation is dire.
Im talking generally here, but from my perspective of a student of law and political science, the general cultural sense in Canada is one of acceptance, diplomacy diplomacy diplomacy, let the other guy do the warring, and then step in when it matters most.
