Thunder Bay Property History Reports
Thunder Bay property history reports pull from City of Thunder Bay open data: building permits published from 2014 with their current status and declared construction value, the zoning applying to the address under Zoning By-law 1/2022, lot area from the municipal parcel layer, the installation age of the water and sewer mains serving the property, and fire station and hydrant proximity. Coverage is the City of Thunder Bay.
What's Included in a Thunder Bay Property History Report
Building Permits, With Open and Closed Status
Permit history from City of Thunder Bay open data, published continuously from 2014. The City records a status on every permit, so the report states whether each one is closed, issued, has occupancy permitted, or is an application still under review. Most municipalities publish the issuance date alone, which is why reports elsewhere can say a permit was taken out but not whether the work was ever finalled. An issued permit that was never closed stays with the property when it changes hands.
Declared Construction Value
The City publishes the declared value of the work on the permit, so the scale of past construction on a property is visible alongside its description rather than left to inference.
Zoning Under By-law 1/2022
The zone applying to the address, with its plain-language description and land use designation, read from the City's own GIS portal. Zoning comes from By-law 1/2022, adopted April 11, 2022, which replaced the City's 2010 by-law. Where Schedule C site-specific regulations apply to the address, those are shown as well.
Water and Sewer Main Age
The City publishes an installation year on its water mains, with records reaching back to the 1910s, and a construction date on its sanitation mains. The report gives the age of the municipal servicing nearest the address, which is the one age signal available for a Thunder Bay property when the age of the house itself is not on the public record.
Lot Area & Parcel Match
Lot area and parcel identifier from the City of Thunder Bay parcel layer, used to confirm the report describes the right property rather than a nearby address.
Fire Station & Hydrant Proximity
Distance to the nearest Thunder Bay Fire Rescue station and to the nearest municipal hydrant.
Radon Risk
Radon prevalence context for Ontario, drawn from the Cross-Canada Radon Survey.
What a Thunder Bay Report Does Not Cover
Year built is usually not available. Ontario assessment data is licensed through MPAC rather than published openly, the City publishes no construction year on its building or property layers, and the permit record begins in 2014, so a construction year is shown only where an original building permit falls inside that window. It is never inferred from a permit for a garage, deck or pool, and the age-based guidance that depends on a construction year is withheld rather than estimated.
Floodplain mapping is administered by the Lakehead Region Conservation Authority and is not published as open data, and the City publishes no queryable floodplain layer, so the report omits flood rather than implying a property sits outside one. The permit record names no builder or contractor, and Ontario land title is not part of the report. The report shows what the public record supports and names the rest as unavailable rather than leaving a gap unexplained.
