Acting with Due Diligence as an Owner under the OHSA
Key Takeaways
The Ontario Superior Court of Justice recently provided insight into what steps an owner must take to establish a defence of due diligence and avoid liability under the Ontario Occupation Health and Safety Act, R.S.O. 1990, c. O.1 (“OHSA”).[1]
Last year, the Supreme Court of Canada greatly expanded the legal liability of owners who engage a constructor on their project in the decision of R v Greater Sudbury (City).[2] In short, the Supreme Court ruled that owners who engage a “constructor” are “employers” under the OHSA and, therefore, are liable for all health and safety violations that occur throughout the course of a project. You can find our previous article about the Supreme Court’s decision here.
The Supreme Court held that owners could avoid liability under the OHSA by demonstrating due diligence. While the Supreme Court identified principles for lower courts to apply as part of the due diligence analysis, the Court ultimately remitted to the Ontario Superior Court of Justice the question of whether the City of Greater Sudbury (“City”) acted with due diligence.
The Superior Court’s recent decision, which applies the principles identified by the Supreme Court, provides important insight as to how courts in Ontario will assess whether an owner has acted with due diligence under the OHSA. Discussed below, the Superior Court confirmed the trial decision of the Ontario Court of Justice that the City acted with due diligence.[3]
Background
The City contracted Interpaving Limited (“Interpaving”) to repair a watermain. The contract provided that Interpaving would assume control over the entire project, including the role of “constructor” under the OHSA.
A pedestrian was struck and killed while attempting to cross the street. No fence was erected between the project and public intersection and no signaller was on site as required by Construction Projects, O. Reg. 213/91 (the “Regulation”). The Ministry of the Attorney General (“MAG”) charged the City with, amongst other things, being an employer under s. 25(1)(c) for failing to ensure that appropriate safety measures were in place.
As discussed in our previous article, the Supreme Court found that the City was an “employer” under s. 1(1) of the Regulation for various reasons. After finding that the City had breached certain health and safety measures prescribed by the Regulation, the Court remitted the matter back to the Superior Court to determine whether the City had nonetheless acted with due diligence.
In remitting the matter back to the Superior Court, the Supreme Court identified that relevant considerations may include, but are not limited to:
- the accused’s degree of control over the workplace or the workers there;
- whether the accused delegated control to the constructor in an effort to overcome its own lack of skill, knowledge or expertise to complete the project in compliance with the Regulation;
- whether the accused took steps to evaluate the constructor’s ability to ensure compliance with the Regulation before deciding to contract for its services; and
- whether the accused effectively monitored and supervised the constructor’s work on the project to ensure that the prescriptions in the Regulation were carried out in the workplace.
Analysis of the Due Diligence Defence
As described below, the Superior Court, applying the principles identified by the Supreme Court, concluded that the trial judge made no palpable or overriding error in finding that the City had acted with due diligence.
