For a Sarnia closing, Treadstone Law works entirely online — no office visit, just a flat, HST-included fee whether you're buying a home, selling one, or registering a mortgage. Book your Sarnia file online and we'll take it from there.
Our charges include HST. Disbursements and, on a purchase, Land Transfer Tax are extra and billed at cost — itemized upfront, in writing, never hidden.

The Sarnia-specific mechanics we handle on every file — so nothing surprises you at closing.
Sarnia properties register through the Lambton Land Registry Office (LRO #25), with the actual registration completed electronically through ONLAND (Teraview) — the electronic system our whole process is built on, so a Sarnia closing runs through the same online steps as any file we handle.
You don’t “set up” property tax — we prorate it. The statement of adjustments credits whoever prepaid; after closing, the municipality bills you directly and you can enrol in pre-authorized payments.
ID verification, document review, and signing happen online — no office visit needed. In-person signings remain available across the province if you prefer.
Sarnia sits within Lambton County, and buyers here pay only Ontario's provincial land transfer tax — there's no municipal land transfer tax on top, since Toronto is the sole exception among Ontario municipalities. We factor that provincial LTT amount into your closing cost estimate from the outset, and flag any first-time buyer rebate you may be entitled to. Sarnia's population was approximately 72,047 as of the 2021 census, and our purchase service applies the same flat fee across the city: $1,354.87, HST included, with disbursements and land transfer tax billed separately at cost.
Financing, inspection, status certificate — your offer’s conditions are legal protections, and waiving them is a legal decision. We review before you sign and flag the risks in plain language.
Buying pre-construction or an assignment carries its own tax and disclosure rules — ask us before you commit so nothing catches you at closing.
When you sell in Sarnia through us, we handle the legal steps completely: discharging your existing mortgage from title, responding to the buyer's requisitions, and releasing your net proceeds once the sale closes. Land transfer tax is the buyer's expense, so it plays no role in a seller's closing costs. Our sale fee is a flat $1,241.87, HST included, and we stay in touch with you through every stage.
Sellers don’t pay LTT. Your closing costs are the legal fee, discharge-related disbursements, and any mortgage payout penalties your lender sets.
We obtain your mortgage discharge statement, answer the buyer’s requisitions, and prorate taxes and utilities on the statement of adjustments.
Funds are wired the day of closing where possible. Selling a condo? We coordinate the status certificate the buyer’s lawyer will request.
Our Mortgage service covers new purchase mortgages, refinances, and private mortgages on Sarnia properties, all at one flat fee of $1,241.87, HST included. We review the commitment letter in detail, register the charge on title, and confirm the lender's conditions are satisfied so funds move as scheduled.
A new charge on a home you already own. We handle the lender’s requirements and register it — one flat fee.
Switching lenders or borrowing more? We manage the payout and discharge of your old mortgage and register the new one.
Borrowing from or lending to a private party. We paper it properly, register the charge, and protect your interests.
You don't need to find office parking in Sarnia — our process is fully online, with document review, signing, and closing all handled online and by phone, so you get complete service without the drive.
No. Neither Sarnia nor Lambton County adds a municipal land transfer tax — that charge is specific to Toronto in Ontario. Sarnia buyers pay the provincial land transfer tax only.
Our legal fee alone: $1,354.87 for a purchase or $1,241.87 for a sale or mortgage, HST already included. The provincial land transfer tax and any disbursements are what falls outside it, billed at their actual cost.
Sarnia property is registered at the Lambton Land Registry Office, LRO #25. Filing is completed electronically through ONLAND (Teraview), a step your flat fee already covers.
