Ontario has no regulation written specifically for working alone. That does not mean there are no rules: under the Occupational Health and Safety Act (OHSA), employers must take every reasonable precaution to protect workers, and working alone is a hazard they are expected to assess and control. This guide explains what that means in practice and how to build a working alone policy for an Ontario workplace.
No single regulation covers working alone in Ontario, unlike Alberta or British Columbia. The obligation comes from the general duty in clause 25(2)(h) of the OHSA: the employer must take every precaution reasonable in the circumstances for the protection of a worker. When an employee works alone, that duty covers the specific risks of being alone: no one to notice an injury, raise the alarm or help.
Working alone is allowed in general, but some regulations require another person to be present for specific work. The best-known example is confined spaces: under Ontario Regulation 632/05, an attendant must be stationed outside the confined space while a worker is inside. Sector regulations can set similar requirements for other high-risk tasks, so check the regulation that applies to your industry.
The OHSA requires employers to assess the risks of workplace violence that may arise from the nature of the workplace, the type of work or the conditions of work, and to put a workplace violence policy and program in place. Working alone, at night, with cash or with the public, is one of the conditions that increases that risk. In practice, your working alone measures often belong in your workplace violence program as well.

A working alone policy is not mandatory as a separate document in Ontario, but it is the simplest way to show that you have taken every reasonable precaution. It should cover:
Ontario law does not set a fixed interval. The interval must match the risk: a low-risk task may only need a check at the start and end of the shift, while hazardous, remote or violence-prone work calls for frequent checks and an automatic alarm if one is missed. Write down who checks, how, how often, and what happens after a missed check-in.
Under section 43 of the OHSA, a worker can refuse work they have reason to believe is likely to endanger them. The refusal must be reported to the employer or supervisor, who must investigate. Some workers, such as police, firefighters or certain health care workers, have limited refusal rights.
A lone worker app does not make you compliant on its own, but it helps you run your procedure reliably. With VigieApp, Neovigie's lone worker safety app:
Yes. Working alone is legal in Ontario, except for specific tasks where a regulation requires another person, such as confined space entry. The employer must still take every reasonable precaution to protect the worker.
No regulation requires a document with that name, but a written policy and check-in procedure is the clearest way to show that you meet your general duty and to align working alone with your workplace violence program.
The employer, with supervisors applying the procedure on a daily basis. Workers must follow the procedure and report hazards.
