In Oil-rich Alberta — home to notorious tar-sands operations — the right-leaning party has been in power there for 44 years. But not anymore. On Tuesday, the lefty New Democratic Party (NDP) won the provincial elections on a platform that promises to diversify Alberta’s fossil fuel–dependent economy. Canada has a multi-party system. The three biggest are the Conservative Party, which is the largest right-of-center party; the Liberal Party, which is center-left and roughly equivalent to mainstream U.S. Democrats; and the NDP, which is like the left wing of the Democratic Party. “We need to start down the road to a diversified and resilient economy. We need finally to end the boom-and-bust roller coaster that we have been riding on for too long,” NDP leader Rachel Notley said.
