About a dozen university students walked into Dominic Leblanc’s office in Shediac this afternoon demanding he sign a letter pledging substantive action on climate change. The sit-in was coordinated with six other student protests across Canada in an effort to halt tar sands expansion. Students occupied MP offices in Victoria, Vancouver, Calgary, Toronto, and Montreal. LeBlanc, the Liberal party’s house leader, has not explicitly addressed the expansion of the tar sands despite voting to “ensure Canada assumes its responsibilities in preventing dangerous climate change.” Student protesters said this contradiction is unacceptable. “We continue to hear political leaders say they’re committed to action on climate change, but their support of tar sands expansion and major industrial infrastructure projects like the Energy East pipeline, run completely counter to those commitments,” said Emma Jackson.
