A provincial veto is the authority of provincial governments to block, override, or cancel municipal decisions. While municipalities have significant autonomy in many areas, provinces retain veto power over certain matters, including major planning decisions, boundary changes, and some financial arrangements. Provincial vetoes can be explicit (requiring provincial approval before a decision takes effect) or implicit (through legislation that overrides conflicting municipal actions). The threat of provincial veto influences municipal decision-making even when not exercised. Municipal associations advocate for limiting provincial veto power to cases of clear provincial interest, arguing local decisions should respect local democracy.
