From Sarnia down through St. Clair Township and nine smaller municipalities, Lambton County closes real estate files on one flat fee, set before you sign anything, with the same online process whether the property is a city lot or a rural parcel.
Lambton County is eleven municipalities in total — Sarnia is by far the largest, with St. Clair Township and Lambton Shores next, then a run of smaller towns and townships like Petrolia, Plympton-Wyoming, Warwick, and Point Edward filling out the rest. Size doesn't change the fee or the file: a closing in Sarnia and a closing in Oil Springs go through the same steps. Purchase files are $1,354.87, sale files $1,241.87, and mortgage refinance files $1,241.87 — flat, taxes included, disbursements and land transfer tax extra at cost.

No. The flat fee is the same across every one of the eleven municipalities in Lambton County, from Sarnia to the smallest township.
The $1,354.87 purchase fee and $1,241.87 sale or refinance fee are flat and taxes included. Disbursements and land transfer tax are separate, charged at cost, and shown on the statement of adjustments.
No — Lambton County properties are subject to the provincial land transfer tax only, with no additional municipal levy.
Development in a regulated area, and interference with a wetland or watercourse, require a permit under section 28.1 of the Conservation Authorities Act, issued by the conservation authority rather than the municipality under O. Reg. 41/24. Watersheds do not follow municipal lines, and Lambton County is reached by two watershed authorities — which one applies depends on where the property drains.
