In Ontario there was the Dryden Municipal Telephone System and the Thunder Bay Telephone Company (now Tbaytel). DMTS was sold but Tbaytel remains owned by the City of Thunder Bay and provides service to various parts of Northwestern Ontario.

And Terra Nova Tel which provided phone service in parts of Newfoundland was built on the legacy of the former Dominion of Newfoundland Department of Posts and Telephones by Canadian National while the latter was still a federal crown corporation.
