Both prompt a worker to check in. Only one of them puts a trained person on the line when the worker does not answer. This page explains what each one does, who receives the alert, what happens when nobody responds, and what the audit trail looks like.
A lone worker app is software on the worker's phone that prompts safety check-ins and sends an alert when one is missed. A lone worker monitoring service is that app plus a staffed monitoring centre, where a trained operator receives every missed check-in and panic alert, at any hour, and follows the employer's written escalation plan. The app detects the problem. The service responds to it. Most apps sold in Canada route the alert to your own supervisors by default and offer live monitoring, if at all, as a paid add-on.
A lone worker app is a smartphone application that prompts an employee working alone to confirm they are safe at set intervals, offers a panic button, and usually records GPS location. When a check-in is missed or the panic button is pressed, the app sends an alert. Where that alert goes is the part most product pages skip. In most apps the default recipient is a supervisor, a coworker or a contact list inside your own organization. The app has done its job when the notification has been delivered. Whether anyone acts on it is up to you.
A lone worker monitoring service combines the check-in tool with a staffed monitoring centre. Every missed check-in and every panic alert is received by a trained operator whose job is to respond, 24 hours a day, following an escalation plan the employer wrote in advance. The operator tries to reach the worker, notifies the designated emergency contacts if the worker cannot be reached, and records every step with a time stamp. The service has done its job when the right people know and the record exists, not when a notification has been sent.
The distinction matters because the two products look identical on the worker's phone. The difference is entirely on the other end of the alert.
Ask a vendor these three questions and the category becomes obvious.
| Question | Lone worker app | Lone worker monitoring service |
|---|---|---|
| Who receives the alert? | A supervisor, coworker or contact list inside your organization, on their own phone. If live monitoring is offered, it is usually a paid add-on, sometimes through a third-party company. | A trained operator at a staffed monitoring centre, as the standard service. With CheckMate, that is ProTELEC's own Five Diamond certified centre in Winnipeg. |
| What happens when nobody answers? | The alert sits in a notification tray until someone sees it. At 2 a.m., on a weekend, or during a supervisor's own emergency, the response depends on whether a contact happens to be awake and reachable. | The operator calls the worker, then works through the employer's escalation list in order until a designated contact is reached, sharing the worker's GPS location and alarm details. The same response at 2 a.m. as at 2 p.m. |
| What is the audit trail? | A log of check-ins and alerts sent. What happened after the alert, and when, is assembled by the employer, if at all. | A time-stamped record of every check-in, every alarm, every call the operator made and every contact notified, exportable for an inspector, a WCB claim or an internal review. |

This is the scenario that decides which product you need, so it is worth walking through both versions.
The worker's check-in window closes. The app pushes a notification to the supervisor on the escalation list. The supervisor is asleep, driving, in a meeting, or has notifications silenced. Nothing else happens until that person looks at their phone. If the app allows a second contact, the same thing repeats. There is no one whose only task is to notice. The procedure the employer wrote down exists, but at that moment nobody is running it.
This is the sequence a CheckMate operator follows. The timings between steps are set by the employer in the escalation plan, and every step is logged with a time stamp.
The worker is prompted through the Safe Alone app, an automated phone call to any landline or cell, a Bluetooth Smart Button, or a satellite device. One tap or one call confirms they are safe and resets the timer.
When the confirmation does not arrive within the window the employer set, an alarm opens at ProTELEC's monitoring centre in Winnipeg with the worker's name, schedule, last known location and emergency contacts on screen.
A trained operator calls the worker directly. Most missed check-ins end here: a forgotten tap, a dead battery, a shift that ran long. The operator confirms the worker is safe and closes the alarm.
If the worker cannot be reached, the operator works through the employer's escalation list in order, notifying the designated emergency contacts and sharing the worker's GPS location and the details of the alarm.
The designated contacts decide whether to send a colleague, attend themselves, or involve emergency services. CheckMate operators do not dispatch emergency services; they make sure the right people know, fast, and stay available to support the response. Every action is recorded for the compliance file.
If no designated contact can be reached either, CheckMate offers an optional Guard Wellness Check, where the operator sends a licensed security guard to the worker's last known location. That step exists precisely because "nobody answered" is the failure mode an app cannot solve on its own.
Most lone worker apps are built as software businesses. Running a monitoring centre is a different business: trained staff on shift around the clock, certified facilities, redundant telecom, and a response procedure that has to work every time. So the typical app vendor either leaves the response with the customer, or resells it as an optional tier through a monitoring partner, in some cases a company in another country.
Of six products reviewed for the Canadian market in July 2026, one routes alerts to the employer's own monitors by design and does not advertise live monitoring at all, one offers it as an add-on through a US monitoring company, two offer it as an optional service, and one offers 24/7 response services alongside protocols the customer defines. CheckMate was the only one of the six where 24/7 live monitoring at the vendor's own centre is the core service rather than an upgrade. The per-vendor detail is in the best lone worker apps in Canada comparison.
This is not a criticism of app vendors. It is a reason to read the pricing page carefully. A low per-user price for software only is a fair price for software only. The question is who is doing the monitoring, and whether that person is paid to be awake.
No Canadian regulation names a product category. What the regulations describe is a procedure with a human response in it. British Columbia's OHS Regulation is the most explicit. Section 4.21 requires the employer to develop and implement a written procedure for checking the well-being of a worker assigned to work alone or in isolation, and says what it must contain:
"(2) The procedure for checking a worker's well-being must include the time interval between checks and the procedure to follow in case the worker cannot be contacted, including provisions for emergency rescue.
(3) A person must be designated to establish contact with the worker at predetermined intervals and the results must be recorded by the person."
Occupational Health and Safety Regulation, B.C. Reg. 296/97, section 4.21. Primary source at WorkSafeBC.
Three things in that wording map directly onto the table above. "The procedure to follow in case the worker cannot be contacted" is the nobody-answers column. "A person must be designated" means someone specific, not whoever sees the notification. "The results must be recorded" is the audit trail. Alberta's OHS Code Part 28 takes a similar line: section 394 requires an effective communication system between the worker and persons capable of responding to the worker's needs, with contact at intervals appropriate to the nature of the hazard. Saskatchewan, Manitoba, Quebec, New Brunswick, Prince Edward Island, and Newfoundland and Labrador each have working alone provisions of their own; Ontario and Nova Scotia rely on the general duty to take every reasonable precaution.
An app can satisfy these requirements if the designated person is genuinely available to act on every alert, every hour the worker is on shift, and the results are recorded. A monitoring service is built so that this is true by default. The province-by-province detail, with primary sources, is in the working alone legislation guide.
CheckMate is the monitoring service of ProTELEC, a Winnipeg company that has operated a monitoring centre since 1968 and launched CheckMate in 2003. The centre is Five Diamond certified, staffed by trained operators 24 hours a day, 365 days a year, and handles more than 3.8 million safety checks a year for 900 and more Canadian organizations. Monitoring is included in the per-user price, from $17.50 per user per month, with no setup fees and no long-term contract. For how the full system works, see lone worker monitoring in Canada.

Sometimes. Regulations such as BC OHS Regulation section 4.21 and Alberta OHS Code Part 28 require a procedure for checking on the worker and a way for someone to respond when the worker cannot be reached. An app satisfies this only if a designated person is reliably available to act on every alert, at every hour the worker is on shift, and the results are recorded. If that person is sometimes driving, in a meeting or asleep, the procedure exists on paper but not in practice. A monitoring service closes that gap because the response is staffed around the clock.
Usually not by default. Of six lone worker products reviewed for the Canadian market in July 2026, most route a missed check-in to the employer's own supervisors or monitors as standard. Where 24/7 live monitoring is available it is typically an optional add-on, in some cases delivered by a third-party monitoring company in another country. CheckMate is the exception reviewed: 24/7 live monitoring at ProTELEC's own Five Diamond certified centre in Winnipeg is the core service, included in the per-user price.
No. When a worker cannot be reached, CheckMate operators notify the designated emergency contacts the employer chose and share the worker's location and alarm details. Those contacts decide whether to involve emergency services. This keeps the decision with the people who know the worker and the site, and it is documented every time.
App-only tools sit at the low end of per-user pricing because the employer is doing the monitoring. Monitored services cost more per user because a 24/7 operator is part of the price. CheckMate starts at $17.50 per user per month with 24/7 monitoring, the Safe Alone app, GPS, the supervisor dashboard and compliance reporting included, with no setup fees or long-term contract. Details are on the pricing page.
CheckMate can. Workers near a landline or with a basic cell phone check in by automated phone call and PIN, workers who need a wearable can use the SOS pendant, which is a standalone cellular device with its own SIM, GPS, fall detection and two-way voice, and remote sites are covered by a satellite device on the Iridium network. All of them report to the same monitoring centre and the same escalation plan.
