Contractor Not Paid in Ontario? Here's How to Recover What You're Owed

What Can Contractors Do If They Are Not Paid in Ontario?

In Ontario, unpaid construction invoices are one of the most common legal disputes involving contractors, subcontractors, renovators, and tradespeople. Many businesses complete the work, supply materials, and finish projects on time — only to face delayed payment, partial payment, or no payment at all.

If a client, owner, or general contractor refuses to pay, there may still be legal options available. Depending on the situation, contractors may be able to send a formal demand letter, register a construction lien, or start a Small Claims Court proceeding to recover unpaid money.

Can Contractors File a Construction Lien in Ontario?

Under Ontario’s Construction Act, contractors and subcontractors may have the right to register a construction lien against a property when payment is not made. A construction lien can place legal pressure on the property owner and may help preserve the contractor’s right to recover unpaid funds.
