How do I track change orders during my Toronto reno?

Tracking change orders properly is one of the most important things you can do to protect yourself financially during a renovation — and it's an area where many Toronto homeowners get burned.

A change order is any modification to the original scope of work, whether it's adding a pot light, upgrading materials, or dealing with unexpected rot behind a wall. Every single change, no matter how small, should be documented in writing before the work begins. A verbal "yeah, sure, we can do that" from your contractor is not a change order.

The core elements every change order document should include:

• A clear description of the work being added, removed, or modified
• The exact cost impact (increase or decrease to the contract price)
• The timeline impact — does this push your completion date?
• Signatures from both you and the contractor
• A reference number tied to your original contract

Setting up your tracking system doesn't need to be complicated. A simple spreadsheet works well for most homeowners. Create columns for: change order number, date requested, description, cost, approval status, and who authorized it. Keep a running total so you always know your current project budget versus your original contract price. Some homeowners use apps like Buildertrend or CoConstruct if their contractor uses them, but a Google Sheet you control yourself is perfectly effective.

In the Toronto market, where a mid-range kitchen renovation runs $40,000–$80,000 and a full home reno can easily hit $200,000+, change order creep is a real budget killer. It's extremely common for projects to run 10–20% over budget due to untracked changes — that's $4,000–$16,000 on a mid-range kitchen alone. Older Toronto homes (think The Annex, Leslieville, East York) are especially prone to surprise discoveries like knob-and-tube wiring, asbestos, or deteriorated framing that generate legitimate change orders.

The golden rule: nothing gets built, nothing gets ordered, nothing gets changed until you have a signed change order in hand. A reputable contractor will not push back on this — it protects them too. If a contractor resists putting changes in writing or pressures you to approve verbally "to keep things moving," treat that as a serious red flag.

Keep all your change orders in a dedicated folder alongside your original contract, permits, and invoices. At project completion, your final payment should reconcile against the original contract price plus all approved change orders. If those numbers don't match, you have documentation to stand on.

Your next step is to establish this process before your project starts — ideally by including change order language directly in your contract. If you haven't started yet, browse the Toronto Construction Network directory to find contractors who operate with professional documentation standards from day one.
