Ontario Premier Kathleen Wynne will remain the least popular premier in Canada heading into 2017, according to an Angus Reid Institute poll released Tuesday.

Wynne's approval rating dropped to an all-time low of 16 per cent in the last quarter of 2016, the online survey that had 5,300 respondents found. This marks the second quarter in a row the Liberal premier has taken the top spot as most unpopular provincial leader. The premier's government has faced political fallout from its decision to sell Hydro One, which critics say could drive electricity prices higher.

The Canadian Union of Public Employees recently filed a lawsuit against Wynne and two other cabinet ministers to halt the sale. CUPE claims the Liberals were in conflict holding fundraisers attended by investment bankers who profited from the privatization. 

Saskatchewan Premier Brad Wall remained the most popular premier with 58-per-cent approval rating. Wall, who has been a long-time opposer to the federal government's carbon pricing strategy, recently refused to sign on Ottawa's national climate plan.

Nova Scotia Premier Stephen McNeil experienced the largest drop in popularity in the last three months, as his government continues to face a labour dispute with the province's teachers union.
