On March 13, 1958, CKAC raised its power to 50,000 watts full-time, using a directional antenna pointing east using two towers, as it moved to its current transmitter site located in Saint-Joseph-du-Lac, just west of the Island of Montreal. The station now had one of the best signals in Eastern Canada, which was quite an exceptional situation for a privately owned station. In the early days of radio in Canada, the CBC used its dual role as regulator and broadcaster to ensure that most of the country's clear-channel allocations went to CBC-owned stations.
