Tax Sale Research
Research notes and methodology for organizing Canadian municipal tax sale notices, maps, and public records.
Research methodology
We organize tax sale data by source document, municipality, province, date, property identifiers, and map context.
Source preservation
Preserving source PDFs, spreadsheets, and public links helps users understand where a listing came from and what still needs official verification.
Quality signals
Useful quality signals include exact lot numbers, matched municipality, verified map context, sale date confidence, and complete financial fields.
