Pursuant to his powers under Radiocommunication Act (Can.), minister of industry authorized R Inc. to install antenna system on certain property in respondent municipality for purpose of improving its cellular telephone network. Municipality, arguing that health and well-being of people living near such installation would be at risk, adopted municipal resolution authorizing service of notice of establishment of reserve (notice of reserve) that prohibited all construction on property in issue for two years pursuant to Cities and Towns Act (Que.) and Expropriation Act (Que.). Few days before notice was due to lapse, it was renewed for two additional years. R Inc. filed motion to contest notice. Motion judge annulled notice of reserve and its renewal, as well as resolutions on which they were based. Appeal from motion judge’s decision was allowed. R Inc. appealed. Appeal allowed. In light of purpose and effects of notice of reserve, its pith and substance was siting of radiocommunication antenna system, which represented exercise of federal jurisdiction. Notice was ultra vires province. In circumstances, notice impaired core of federal power over radiocommunication in that it compromised orderly development and efficient operation of radiocommunication in Canada. In addition, it was inapplicable to R Inc. by reason of doctrine of interjurisdictional immunity.
