Two of Canada’s largest provincial law firms announced their intention to merge on Wednesday. The union, the latest in a series of combinations between firms up north, will create one of the largest full-service firms in western Canada.

The proposed tie-up between Winnipeg-based Aikins, MacAulay & Thorvaldson and Regina-based MacPherson Leslie & Tyerman (MLT)—the largest firms in Manitoba and Saskatchewan, respectively—is expected to go live on Jan. 1, 2017.
