The Construction Lien Court

Rights and obligations in the construction industry.

The Construction Lien Act, R.S.0. 1990 c. C30, places rights and obligations on participants in the construction industry that control the flow of funds in virtually all construction projects. While these rights and obligations are complicated, they are not always clearly understood, and the failure to properly manage them can have significant consequences. Opportunities for early and satisfactory resolutions, for example, are often overlooked or misinterpreted.

We bring our knowledge of the pitfalls and remedies associated with the Act to bear in representing our clients. Our experience in this regard has also resulted in our being asked to prepare and present many papers, speeches and seminars on these issues, to other lawyers, and to industry groups.
