The appellant, an aerodrome operator, appealed a decision declaring that a municipal fill by-law applied to its landfill activities.
The appellant argued the by-law was inapplicable under the doctrine of interjurisdictional immunity because aerodromes fall under federal jurisdiction.
The Court of Appeal dismissed the appeal, upholding the application judge's finding that the by-law regulates the quality of fill for environmental protection and does not impermissibly trench on the core of the federal aeronautics power.
