Information Services Corporation maintains that registry for the whole province, so a title search pulls directly from a single authoritative source rather than a patchwork of municipal records, and that search confirms who legally owns the property and whether anything, a lien, an easement or an unregistered agreement, is attached to it.
Owner's title insurance is optional in Saskatchewan, unlike the lender's policy a mortgage typically requires, and it protects against a defect the Information Services Corporation search did not catch, fraud, an old unregistered claim or a boundary problem, for a one-time premium usually folded into legal fees of $800 to $1,500.
Your lawyer's search and the registry itself are what actually protect your ownership, not a physical document you keep in a drawer. Get your hand-reviewed valuation from Joel Dyck.
