VPN & Proxy Detection — CanadaDetect VPN, Proxy & Bot Traffic from Canada
Maskbreak scores every visitor's network in real time — flagging VPN exit nodes, residential proxies, datacenter ASNs, and headless browsers originating from Canada. Free API. Under 40ms server-side. No CAPTCHAs.
The networks Canada traffic actually arrives from
Canada has 1,614 autonomous systems on the public registry. 176 of them are hosting, cloud or transit networks holding 47.4M addresses between them — the ranges a commercial VPN or datacenter proxy exits from. Residential broadband is the rest, and that is the traffic worth watching, because a residential proxy hides inside it.
| ASN | Network | IPv4 space |
|---|---|---|
| AS577 | BACOM | 6.8M addresses |
| AS812 | ROGERS-COMMUNICATIONS | 5.7M addresses |
| AS6327 | SHAW | 5.3M addresses |
| AS852 | TELUS Communications | 4.8M addresses |
| AS5769 | VIDEOTRON | 2.7M addresses |
| AS808 | GONET-ASN-1 | 1M addresses |
| AS7992 | COGECOWAVE | 989K addresses |
| AS376 | RISQ-AS | 922K addresses |
Largest hosting-shaped networks registered in Canada, by IPv4 allocation. Registry data, refreshed daily. A datacenter ASN is not evidence of fraud on its own — it is one signal, weighed alongside device and behaviour.
Why Canada traffic needs special scrutiny
Datacenter ASN concentration
OVH's Beauharnois datacenter ASN is a top origin of cross-border SaaS account abuse targeting Canadian platforms.
Residential proxy resale
Consumer ISP ranges in Canada can appear in commercial or peer-to-peer residential proxy pools. A consumer ISP label is not proof of fraud; combine it with device, session, and routing signals.
VPN exit-node clustering
The same handful of hosting providers dominate VPN exit nodes in Canada. Maskbreak maintains live mappings of these ranges so a new IP from a known VPN ASN is flagged within seconds of going live.
Antidetect browser usage
Multi-accounting fraud against Canadian-targeted SaaS, fintech, and e-commerce increasingly uses Kameleo, GoLogin, or AdsPower to spoof device fingerprints. Maskbreak scores these at the device layer, not the IP layer.
What Maskbreak detects for Canada traffic
- Every major VPN provider's Canadian exit nodes (NordVPN, ExpressVPN, ProtonVPN, Mullvad, Surfshark, and 40+ more)
- Commercial or peer-to-peer residential proxy pools using consumer Canadian IPs
- Datacenter ASNs commonly used for automation (AWS, GCP, Azure, OVH, Hetzner, DigitalOcean, Vultr, Linode)
- Tor exit nodes and known anonymous relays advertising Canadian geolocations
- Headless browsers (Puppeteer, Playwright, Selenium) and antidetect tooling driving sessions from Canada
- Country-spoofing — when a session claims to be in Canada but the network telemetry says otherwise
