ISC maintains the Land Titles Registry for the whole province, and anyone can order a title search showing the registered owner, the legal description and any interests registered against the property, such as a mortgage or a caveat. A lawyer typically runs this search as part of the $800 to $1,500 legal fee for a purchase or sale, and flags anything unusual before possession changes hands.
If you are the seller, checking title before you list means no last-minute surprise about an old lien or an unresolved caveat. If you are a buyer, your lawyer confirms title is clean at possession, which is a different sequence from how a home purchase closes in some other countries.
A title problem almost always shows up as a delay, not a lost sale, and a good lawyer catches it long before possession day. Get your hand-reviewed valuation from Joel Dyck.
