Unknown caller
Got a callfrom a Ontario number?
A Ontario area code shows where the number was first assigned, not where the caller is now. People keep their numbers when they move, and scammers often fake local-looking numbers.
- Don’t know the number? Let it go to voicemail.
- Says it’s your bank or a government office? Hang up and call the number on their website or your card.
- Never share codes, passwords or card details with a caller.
- Report scam calls to the Canadian Anti-Fraud Centre.
Need to call your bank or an office back from abroad? GlobCall calls the official number from your browser for $0.02/min, instead of the $1 or more a minute many carriers charge.
