Public notice requirements are provincial rules mandating that municipalities inform the public about meetings, decisions, and opportunities for input. Requirements typically specify that notice be published in local newspapers, posted at municipal offices, or now increasingly, published online. Notice periods vary by type of decision—planning applications might require 20 days notice while regular council meetings need only 48 hours. Public notice requirements ensure citizens have reasonable opportunity to learn about decisions affecting them and participate in the democratic process. Failure to provide proper notice can invalidate municipal decisions, so staff carefully track notice requirements.
