New regulation sets fees, forms and deadlines for Metrolinx building-code compliance notices to chief building officials

NOTIFICATION OF THE CHIEF BUILDING OFFICIAL — under the Metrolinx Act, 2006

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

A new regulation spells out the procedural rules that apply when Metrolinx (the Corporation) must notify a chief building official about construction on its properties. It requires Metrolinx to pay whatever fees a municipality has set under the Building Code Act, and specifies that related municipal by-laws on fee adjustments also apply. Compliance reports must use the prescribed "Building Code Compliance Report" form and must be delivered within 30 business days of the chief building official receiving the initial notice. Subsequent inspection and occupancy-opinion steps each carry a 10-business-day deadline, though both can be extended by written agreement between Metrolinx and the relevant official or registered code agency. Affected parties — chiefly Metrolinx project teams and the municipal building officials and registered code agencies they deal with — should update their workflows and templates to reflect the new form requirement and statutory timelines.

Who this affects: Metrolinx project and construction teams · chief building officials in municipalities where Metrolinx builds · registered code agencies acting on Metrolinx projects · municipal finance and permit offices
