Frequently asked questions
Is parcel data available in every province?
No. Coverage for parcels, QHSDD and current-status planning varies by area and dataset. Share the province, ward or coordinates you need so GMap can confirm.
Are results legally binding?
The data supports lookup and initial investigation. Decisions must be checked against documents from the competent authority.
How do I find the former ward code?
Use the former administrative unit catalogue API, or look up the parcel by coordinate when you don’t have the code.
