Property lines by address
Understand your lot. See what fits. Province-wide coverage in British Columbia, Quebec and New Brunswick, plus selected major Canadian cities. The planner turns those lot lines into a project test: building footprint size, yard, and what might fit.
One of Canada’s most comprehensive residential lot-planning tools for homeowners. Free to use. Planning estimates — not a survey, title search, or construction approval.
The lot line is not scarce. Professional databases and city GIS already have it. What is scarce is putting the lot, the house, the yard, and a project test in one place a homeowner can open without a subscription.
MyLotFit combines several things that usually exist separately:
| Source | What it is for | What it does not do for a homeowner |
|---|---|---|
| Regrid | Parcel data, GIS, and professional workflows. It says it has more than 10 million Canadian parcels. | It is not a backyard planning tool. You still have to decide whether a pool or a laneway house fits. |
| GeoWarehouse | Authoritative Ontario ownership, title, sales, and lot information for due diligence. | It is built for lawyers, lenders, and agents — not a free sketch of what might fit in the yard. |
| Québec Land Register and other provincial registries | Legal property records. | They prove title. They do not test a court, deck, or parking pad on your lot. |
| Municipal GIS | The official lot fabric for that city or province — the same outlines we query. | Each site is different. Most stop at the parcel. Few show a usable yard or a project envelope. |
| MyLotFit | A free residential planning tool: public lot line, building outline where we have one, aerial or streets, and automatic fit tests. | Not a survey, title search, or sales history. Shallower legal data — on purpose. |
Those other products are generally for professionals, data customers, or legal research. MyLotFit answers a more approachable question: what is on my lot, and what might I be able to do with it? The site is free because the outlines come from public records and because the planner is the product — not a GIS extract for sale. Looking up an address and running Show me what fits does not require an account.
Before we talk about Canada in marketing copy, the coverage has to be specific. Below is the list we will stand behind: where lot outlines come from, whether a building footprint may appear, how fresh the geometry is, and how we count population. We do not publish a national “residential parcel” total. The layers we query include every parcel type the source publishes — houses, apartments, commercial, parks, and rights-of-way — and we ask them live instead of hosting a counted fabric.
| Province / region | Coverage | Lot outline | Building footprint | Source and freshness |
|---|
These cities sit outside the three province-wide fabrics. Each uses that city’s published parcel polygons. Civic address labels appear where the city also publishes an address layer.
| Municipality | Lot outline | Building footprint | 2021 Census population | Source and freshness |
|---|
In British Columbia, Quebec, and New Brunswick the list is the province, not a handful of downtowns. Montréal, Québec City, Laval, Gatineau, Vancouver, Surrey, Victoria, Kelowna, Moncton, Saint John, and Fredericton are included because those provincial fabrics cover them — not because we invented a city file.
| What you see | Kind | How we get it |
|---|---|---|
| Lot outline | Reported | Public municipal or provincial parcel geometry, queried live. |
| Lot dimensions and area | Calculated | Measured from that outline. Not a surveyor’s closure. |
| Building footprint | Reported, where available | OpenStreetMap North America buildings. Missing footprints are common. |
| Building footprint size | Calculated | Approximate ground-level area from the OSM outline. Not interior floor area or living space. |
| Keep-back band | Estimated | A uniform 8 ft sketch envelope, not your by-law setbacks. |
| Object pads (court, pool, deck, greenhouse, parking, laneway) | Estimated | Published play or kit sizes plus the pad we actually test. |
| Show me what fits / conflicts / rotation | Calculated | Geometry tests on this lot and these buildings. Not a permit review. |
| Population covered | Reported | 2021 Census counts for the provinces and cities named above. Not 2026 estimates. |
| Residential parcel count | Not published | We do not host a national residential extract, so we will not invent a parcel total. |
If a municipality does not publish an unauthenticated parcel polygon API, we use a sample 80 × 130 ft yard so you can still plan. Missing records do not invent a lot line.
Coverage exists so a homeowner can open an address and see the lot. The reason to keep the address is what happens next: usable yard, object envelopes, automatic placement, conflict detection, and a downloadable visual report. That combination is what land registries and professional parcel shops do not sell to someone who wants to know whether a pool or a laneway house might fit. How that helps homeowners, realtors, designers, and installers.
