Ontario Parcel & Land Maps
Ontario's land registry is electronic and is searched through OnLand, where parcel registers are sold for a fee. Each registered parcel has a nine-digit Property Identification Number (PIN). The Municipal Property Assessment Corporation (MPAC) gives each property an Assessment Roll Number (ARN). Ontario has no free province-wide parcel map, so the links below are free city maps that show property lines.

A note on accuracy
Online parcel maps are drawn for registry, tax and planning use and are not a survey. For fences, setbacks or a sale, check the registered plan or hire a Canadian land surveyor (an Ontario Land Surveyor, BC Land Surveyor and so on).
