Oct. 11, 2011 -- The Tories are re-elected as Dunderdale leads the party to another majority government.

April 22, 2012 -- After years of healthy surpluses, Dunderdale's government forecasts a deficit of about $400 million for the 2012-13 fiscal year as the price of crude dips and takes its toll on the province's oil-dependent economy.

Sept. 13, 2012 -- Tom Osborne, a long-time member of the Tory caucus, announces he will sit as an Independent, saying he never supported Dunderdale as leader of the party. He later joins the Liberals.

Dec. 17, 2012 -- A ceremony marks the final approval for the hydro project as Dunderdale describes it as a turning point in her province's history, although its passage through the legislature was marked by opposition accusations that the government didn't allow for a full review of the development.

Jan. 9, 2014 -- Dunderdale calls an independent review of the province's electricity system following a week of rotating blackouts that closed schools and businesses.
