Middle powers are said to be those states occupying the middle point in a range of bigness to smallness- usually measured by quantifiable attributes as area, population, size, complexity and strength of economy, military capability, and other comparable factors (Cooper, 1993).
Canada is a middle power, as defined by the preceding quotation, but to a greater extent as well. But it wasn't always this way. After World War I, Canada adopted an autonomous, quite isolationist stance characterized by a refusal to engage in collective decision-making and an avoidance of all commitments, possibly fearing another European war. All that changed, however, in the aftermath of the World War that followed.
