Construction Liens. J.D. Strachan Construction Ltd. v. Egan Holdings Inc.
In J.D. Strachan Construction Ltd. v. Egan Holdings Inc. (Div Ct, 2021) the Divisional Court set out some basics of the construction lien regime:
 The CLA is remedial legislation, to be given a large and liberal interpretation to secure its objects. On the other hand, the courts have consistently construed the deadlines in the Act strictly. There is good reason for this. Registration of a claim for lien gives notice to all the world of a lien claim. This notice is relied upon by other stakeholders, including lenders, owners, and contractors and subcontractors.. Tremblar Building Supplies Ltd. v. 1839563 Ontario Limited
 The CLA provides a mechanism by which an owner may establish – for all the world – that there are no liens in respect to a contract after that contract has reached substantial completion: publication of a certificate of substantial completion in accordance with the Act. When this is done, it starts the clock running: a lien claimant has 45 days to register a claim for lien from the date of publication of the certificate of substantial completion. The lien claimant then has a further 45 days to register a certificate of action. Both dates are calculated from the date of publication of the certificate of substantial completion: 45 days for the claim for lien, and a further 45 days (total of 90 days) for the certificate of action.
 Where there is no certificate of substantial completion, the same deadlines apply, but calculated from the date on which the claimant last supplied services or materials to the improvement.
 In some situations, including the case at bar, two sets of deadlines arise:
(a) deadlines for claims respecting goods and services provided to the date of the certificate of substantial completion, which are calculated from the date of publication of the certificate; andThe deadline in (a) applies up to claims for services and materials to the date the certificate was published; the deadline in (b) applies to work done after publication of the certificate.
(b) where a claimant supplies services or materials after the date of publication of the certificate of substantial completion, the date of last supply of materials or services to the improvement.
In Tremblar Building Supplies Ltd. v. 1839563 Ontario Limited (Div Ct, 2020) the Divisional Court reviewed some basics of the Construction Lien Act (now the Construction Act):
 The Construction Lien Act creates two distinct sets of obligations and remedies relevant to this appeal: the construction lien and the construction trust. These obligations and remedies are in addition to and overlie the contractual rights and obligations between the parties.. R&V Construction Management Inc. v. Baradaran
 This creates three potentially intersecting sets of rights and obligations arising from the same facts. The Construction Lien Act is remedial legislation and provides additional obligations and rights to those provided by the common law. Those additional rights and obligations do not imply the existence of further rights and obligations that do not arise under contract law or the Construction Lien Act.
 This case illustrates this point. But for the Construction Lien Act, Tremblar would be restricted to its rights in contract law. It would have no direct recourse against Owner, with which it had no contractual relationship. If it obtained judgment against Contractor and remained unpaid, then it might have recourse against Owner under either the law of debtor/creditor (if Contractor was not bankrupt), or under the Bankruptcy and Insolvency Act (if Contractor was bankrupt). There would be no Construction Lien Act trust remedies. There would be no remedies for unjust enrichment.
 The Construction Lien Act creates additional rights and obligations, two of which relate to this appeal. The first is the construction lien. Appellant was entitled to assert this right by registering a construction lien. It would have been entitled to a rateable share of the statutory “holdbacks” Owner was obliged to retain from what it paid to Contractor. This creates security and a direct right of action between Tremblar and Owner, a person with which it has no privity of contract – something created by the Act. The appellant chose not to avail itself of this claim and lost it as a result.
 The second relevant regime created by the Act is the construction trust. This is a statutory trust, and it is created by, and limited by, the terms of the Construction Lien Act. The trust runs with contractual obligations, but only in respect to money received or receivable by the trustee in respect to the improvement. Owners do not hold funds in trust for subcontractors. Otherwise, owners would have a positive obligation to ensure that contractors apply their funds properly. Owners do not have that trust obligation under the Act and it would undermine the structure of relations under the Act to find otherwise.
In R&V Construction Management Inc. v. Baradaran (Ont CA, 2020) the Divisional Court engaged in a prolonged consideration of the role of Masters in construction lien litigation [formerly under the Construction Lien Act, now under the Construction Act] [paras 14-42].
