Understanding Construction Liens and the Registration Process

This presentation explains the practical and legal mechanics of registering and preserving a construction lien under Ontario’s Construction Act in situations where a contractor invoices a property owner. It outlines the nature of a construction lien as a statutory security interest that can be registered without owner consent, the importance of priority and timing, and the limits on registration tied to the last supply of services or materials. The presentation emphasizes due diligence through property and corporate searches, careful client intake, and reliance on sworn client information, alongside clear reporting obligations to manage risk. It addresses the distinction between lien registration and perfection, highlighting the requirement to commence an action and register a certificate of action within the statutory period to preserve rights. Practical guidance is provided on electronic registration, document preparation, and client communication, reinforcing how disciplined process and clear advice protect both lien claims and professional responsibility.
