The wireless industry is gradually retiring older cellular networks to accommodate faster, more dependable technology. This transition, called the 3G Sunset, is occurring across Canada from mid-2025 to the end of 2025. For homeowners and businesses that depend on monitored security systems, it’s crucial to understand how this change might impact your protection.
When Will 3G Shut Down in Canada?
-
Rogers began its 3G network shutdown on August 7, 2025.
-
Bell Mobility will retire its 3G service on December 31, 2025.
After these dates, any device that still uses 3G will stop communicating. This includes alarm panels, security communicators, and monitoring devices.
How Will This Affect Security Systems?
Many older security systems in Toronto and across Canada still rely on 3G cellular communicators to transmit alarm signals. Once the networks shut down:
- Systems may display ongoing trouble alerts.
- Some may fail to send emergency signals to the monitoring station.
- Even dual-path systems (Wi-Fi plus cellular) can be disrupted if the cellular communicator is outdated.
For Rogers customers, this loss of service begins in August. Bell customers have until the end of December 2025 before their 3G-based systems lose functionality.
What Should Security Customers Do?
The solution is to upgrade to LTE or 5G-ready communicators. These newer devices provide stronger, faster, and more reliable connections for alarm monitoring.
