Energy accounts for 10% of Canadian GDP and around 25% of exports and the swift fall in oil prices is having a profound effect in the nation's oil producing regions. Take Calgary for instance, where single-family home sales fell 34% last month. As the following chart shows, Alberta derives some 30% of its provincial revenues from energy royalties and as one TD analyst quoted by the Calgary Herald recently noted, "the effects of significantly lower oil prices had already turned up in resale activity, with sales in Calgary and Edmonton down more than 40 per cent and 30 per cent respectively, from October to January [and] as resale activity slows, prices usually follow."

Depressed crude prices will create a $7 billion annual revenue shortfall for the province while GDP growth, which had been running at around 4%, is expected be just under half that this year, with some analysts predicting the economy will contract.
