McKay v R

McKay v R, (1965) S.C.R. 798 is an early election law decision of the Supreme Court of Canada on the constitutionality of laws that limited the erection of election signs. The Court held that a municipal zoning regulation against signs on residential properties could not include federal election signs. The reading down of the municipal by-law to not include Federal election signs evidences an early stage in the evolution of the Interjurisdictional immunity legal doctrine.
