Official plan amendment notices and records no longer require certified copies; Ministry notice can now be sent via Ontario government website

OFFICIAL PLANS AND PLAN AMENDMENTS — under the Planning Act

Plain-language summary · AI-assisted · not legal advice

Several procedural requirements for official plan and plan amendment processes have been updated. Documents submitted in records to the Ontario Land Tribunal and approval authorities no longer need to be certified copies — plain copies are now sufficient. Notices to the Ministry of Municipal Affairs and Housing (the ministry's name is also clarified in the regulation) can now be delivered electronically through a Government of Ontario website in addition to the existing options of personal service, mail, fax, or email. The opt-out language for ministerial-approval cases is also updated to say notice is not required rather than referencing a personal preference. Municipal clerks, planning boards, and approval authorities handling official plan amendments should update their document preparation and notice delivery practices accordingly.

Who this affects: municipal clerks · planning board secretary-treasurers · approval authorities · applicants for official plan amendments · legal and planning staff preparing Tribunal records
