Everything you need to know about buying a home in Sarnia, Ontario — including your Ontario Land Transfer Tax costs, full closing cost estimates, and first-time buyer programs.
Sarnia sits at the southern tip of Lake Huron where it flows into the St. Clair River, bordering Port Huron, Michigan. The petrochemical industry, healthcare (Bluewater Health), and cross-border commerce drive the economy. Bright's Grove beachfront and Point Edward casino-area properties trade at premiums.
Whether you are relocating from the Greater Toronto Area, moving up within Sarnia, or purchasing your first home, understanding Ontario's Land Transfer Tax (LTT) is essential. The provincial LTT applies to every residential purchase in Ontario and can add thousands of dollars to your closing costs.
Ontario's Land Transfer Tax uses a tiered rate structure based on the purchase price:
At Sarnia's median home price of $4300,000000, you would pay approximately $5,0075 in Ontario LTT. First-time buyers qualify for a rebate of up to $4,000000, which can reduce or eliminate LTT on lower-priced purchases. Use the calculator below to see the exact amount for any purchase price.

When buying in Sarnia, explore these areas: Sarnia Bay waterfront, Bright's Grove, Point Edward, Forest, Corunna, Mooretown, and rural Lambton County. Each neighbourhood has distinct character, price points, and amenities. Working with a local REALTOR familiar with Sarnia's micro-markets will help you identify the best fit for your lifestyle and budget.
