Canada’s pipeline map is beginning to look familiar again, with proposals reaching west, east and south. Their names may be different, but each of them echoes a project once promoted and later abandoned. More than a decade ago, the oilpatch was booming with new oilsands facilities under construction — and proposed pipelines that would have moved heavy crude in nearly every direction. Many of the projects, including Keystone XL , Energy East and Northern Gateway , ran into various walls, from strong political opposition to regulatory uncertainty. All these years later, the oilpatch appears to be at a turning point, with newly proposed pipelines and possible production growth to fill them. These new projects carry echoes of the ones that came before. Check out our animations showing how Prairie Connector, Northern Shield and the West Coast pipeline mirror — and differ from — the ghosts of pipelines past. Find out where every line would run, what was left behind and which hurdles could stop them again.
