The applicant sought to quash a municipal by-law imposing a two‑kilometre setback for industrial wind turbines from any “property” as defined in the by-law.
The court held that the definition of “property,” which included property lines, vacant land, structures, and inhabitants “of all species,” rendered the by-law unintelligible and incapable of consistent interpretation.
Because the measuring point for the setback requirement was unclear, developers could not determine where turbines could legally be located.
The by-law was therefore invalid for vagueness and uncertainty.
The court further observed that, even if valid, the by-law could become inoperative where it conflicted with provincial renewable energy legislation and regulations.
