The Globe and Mail reassesses Canada's economic prospects in its Wednesday edition. The Globe's guest columnists David Suzuki and Jeff Rubin write that for almost a decade, Canadians have been told expansion of Alberta's oil sands would be the engine of economic growth. The Tory government's strategy of making Canada an oil-based energy superpower has led instead to a made-in-Canada recession. Ambitious oil sands expansion was based on the assumption of never-ending double-digit growth in China's economy. China's economy is growing at about half its previous double-digit rate. That has left the oil sands in a world of sluggish economic growth. Suddenly Canada's government-driven engine of economic growth looks more and more like stranded assets. The tens of billions of dollars of cancelled investment in oil sands projects profoundly change the national debate Canadians have been having about the supposedly urgent economic need for new pipelines. The Globe says an oversupplied world oil market does not need Canada's high-cost fuel. Whether it is Keystone XL, Northern Gateway or Energy East, none of the proposed pipeline projects make economic sense in today's oil market.
