A minor variance is permission a property owner gets from the local Committee of Adjustment to depart slightly from a zoning bylaw’s specific requirements — a setback, a height limit, a lot-coverage percentage — without changing the zoning itself.
Ontario’s own Citizen’s Guide to Land Use Planning puts the test simply: “If your proposed change doesn’t conform exactly to the zoning bylaw, but follows its general intent, you can apply for a minor variance”. That “general intent” language is the whole test — a minor variance is not a rezoning, and the two get confused constantly.
The application goes to the municipality’s own committee: “you will have to apply to your local committee of adjustment appointed by council to deal with minor problems in meeting bylaw standards”, which “will hold a hearing and decide on your application”, and, once decided, “Any identified person or public body that has an interest in the matter may appeal to the OLT within 20 days” — the Ontario Land Tribunal — so a neighbour’s objection at the hearing isn’t the end of the process either way.
Crucially, an approved minor variance doesn’t rewrite the bylaw: “A minor variance does not change a zoning bylaw. It simply excuses you from a specific requirement of the bylaw and allows you to obtain a building permit”. For a listing agent, that means a property built under an old minor variance stays compliant only for that specific excused requirement — everything else in the bylaw still applies, and a buyer’s own renovation plans may need a fresh variance of their own.
Due diligence on a purchase should confirm whether one is already registered against the property: buyers should “confirm whether any minor variance or site plan approval is registered against the property and whether there are conditions attached” before waiving conditions.
A seller’s detached garage sits four feet from the side lot line where the bylaw requires six. A minor variance approved a decade ago excuses that specific setback for that specific structure. The buyer wants to add a second storey to the garage — the existing variance covers the footprint as built, not a taller structure, so the buyer’s agent flags that a new minor variance application, and a new committee hearing, will likely be needed before that expansion can get a building permit.
