In Alberta, working alone is legal, but it is treated as a hazard. Part 28 of the Occupational Health and Safety (OHS) Code requires employers to assess that hazard, give lone workers an effective way to call for help, and contact them at regular intervals. This guide explains when the rules apply, what employers must do, and how to build a work alone policy that holds up.
Yes. Alberta is one of the provinces with specific working alone requirements. They sit in Part 28 of the OHS Code (Alberta Regulation 191/2021, sections 393 and 394), under the Occupational Health and Safety Act. Working alone is also a hazard that must be covered by the general hazard assessment rules in Part 2 of the Code.
The working alone rules apply when both conditions are met:
If two or more workers are working together, Part 28 does not apply. Government guidance uses three tests to decide whether assistance is readily available:
The higher the risk, the stricter the test: for high-risk work, readily available can mean immediately available. A worker driving the Calgary to Edmonton highway in daytime is usually not working alone; the same worker on a remote logging road, or on a quiet road at night, usually is.

When a worker works alone, the employer must:
If an effective communication system is not practicable at the work site, the employer must instead visit the worker, or make sure the worker contacts the employer at set intervals.
Workers alone at gas stations, retail fuel outlets and convenience stores fall under additional violence prevention requirements, including a personal emergency transmitter monitored by the employer and worn at all times. See the government guide BP031.
The OHS Code does not set a fixed interval. The interval must match the hazard: every few hours may be enough for low-risk office work after hours, while hazardous or remote work calls for much shorter intervals, plus a check at the end of the shift. Your procedure should also say exactly what happens when a worker misses a check-in: who calls, after how long, and when to send help.
A work alone policy turns these duties into a procedure your team can follow. It should cover:
Under the OHS Act, a worker can refuse work they believe presents an undue hazard. The worker must report the refusal to the employer or supervisor, who must investigate and take action.
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:
For remote Alberta sites with no cell signal, Neovigie also works with satellite messengers.
Yes. Working alone is allowed, provided the employer meets the requirements of Part 28 and Part 2 of the OHS Code.
A radio, telephone or other electronic device that connects the worker with someone able to respond, combined with regular contact at intervals suited to the hazard.
They can. Government guidance treats a vehicle as a work site; whether the rules apply depends on whether help is readily available, which changes with the road, the time of day and the hazard.

Working alone is allowed in Quebec, but the employer must protect the worker under section 51 of the Act, and section 322 of the RSST requires an effective surveillance method for lone work in an isolated place.
