This program is part of the OsgoodePD “Deconstructing Ontario’s New Construction Act” Series!

Ontario’s new Construction Act has overhauled construction law rules and has significantly changed the construction liens process. To avoid costly missteps, you must have a clear grasp of how to navigate the changes.

Developed for industry professionals and their advisors, this one-day intensive OsgoodePD program will give you a crucial overview of the new liens regime in Ontario along with practical strategies and tactics that you can immediately put to use when navigating your next lien matter.

Learn from an expert multi-disciplinary faculty, including perspectives from decision-makers. You will work through the lien trial process, obtain valuable resources, best practices, and learn which tactics to use – or avoid – in your lien matters. Topics include:

  • When do liens arise? When do they expire?
  • How to recognize and differentiate the various types of liens
  • Understand the mechanics of how to preserve, register and give a lien – including vacating, discharging and perfecting
  • What is the liability for exaggerated liens?
  • Troubleshooting tips – what to do when there are two subcontracts issued to one trade (2 liens)? Federal land?
