Who has authority over antenna installations, including antenna masts and towers?

Under the Radiocommunication Act, the federal government has exclusive jurisdiction over radiocommunication in Canada. This means that the ultimate authority over all antenna installations, including masts and towers, lies with the Minister of Innovation, Science and Industry. While local municipalities and land-use authorities are involved in the consultation and planning process to address community concerns, they do not have the final legal authority to approve or deny an installation. Distractors suggesting that provincial ministers, local governments, or a majority vote of neighbors have final authority are incorrect because radio waves and their associated infrastructure are strictly a federal matter.
