British Columbia, served today by Telus, was served by numerous small companies that mostly amalgamated to form British Columbia Telephone, later known as BC Tel (the last known acquisition was the Okanagan Telephone Company in the late 1970s), which served the province from the 1960s until its merger with Telus. (The amalgamations produced one anomaly: Atlin is surrounded by the territory of Northwestel, implying that the company that established service there was acquired by a company serving territories further south.)
