Only a few years ago, energy dominated the Canadian economy. From oil sands to pipelines, uranium to shalle gas and with major hydro projects on the drawing boards, this country seemed unique placed to mobilize it's energy resources to produce sustained national prosperity. The picture is different now. Protests surround major projects. Pipeline projects have either failed or stalled. Oil and gas prices fell dramatically. Globally, the transition from "peak oil" to an energy "glut" occurred with stunning speed. The reality remains that Canada is a true energy super power, with a diversity of resources and abundant supply, in a world with a growing population and increasing energy needs. This presentation contemplates the future of Canada's energy sector in light of medium and long-term realities, the climate change debate and shifting government policies.
