Your alarm system is only as good as the people watching it. The monitoring centre is where the signal goes when your alarm triggers — and their response determines whether police arrive in 3 minutes or 30. Here's how to evaluate monitoring companies.

ULC Certification Is Non-Negotiable

ULC (Underwriters Laboratories of Canada) certification means the monitoring centre meets strict standards for staffing, redundancy, power backup, and response procedures. Your insurance company likely requires ULC certification for your alarm discount. If a monitoring company can't show you their ULC certificate, keep looking.

Response Time Matters

Ask this question: "How long from alarm trigger to police dispatch?" The answer should be under 60 seconds. Some budget monitoring services batch their alarms and process them in order — meaning your alarm might wait in a queue. Premium centres have operators dedicated to real-time response.

False Alarm Handling

False alarms are expensive — most Ontario municipalities charge $100-350 per false alarm dispatch after your first few. A good monitoring company verifies alarms before dispatching: calling your contacts, checking camera feeds, or using two-way audio. This verification step dramatically reduces false alarm fines without slowing response to real events.

Redundancy

What happens if the monitoring centre loses power? Or their phone lines go down? Premium centres have backup power (72+ hours on generator), redundant communication paths (multiple carriers), and geographic redundancy (a second centre that takes over automatically). Ask about their disaster recovery plan.

Local vs National

A monitoring centre that knows Mississauga from Milton matters. Local centres understand the geography, have relationships with regional police dispatchers, and provide faster, more relevant response. National centres are cheaper but generic — the operator dispatching police to your building might not know what province you're in.
