Spam calls — or “scam calls” as they’re also known — have become an infuriating part of life. By now, most people are well acquainted with fraudsters trying to dupe you out of your cash by impersonating government officials or Amazon employees.
“I’m still getting a lot of spam calls,” said Pradeep Selvaraj, an IT professional in Whitby, Ont., who has posted about the issue on his YouTube channel.
Salvaraj estimates he receives two to three calls a week from scammers — often while at work. They claim they’re from the “CRA, RCMP, duct cleaning, Amazon, UPS shipping and the list goes on,” he said. “It’s very annoying.”
Many people had high hopes such calls would stop when, in late 2021, the CRTC introduced with much fanfare, new technology called STIR/SHAKEN. It lets telecoms detect and flag calls that use spoofed or altered phone numbers to disguise their true identity.
But STIR/SHAKEN was never meant to be more than a partial solution and, some 18 months later, has yet to be entirely implemented. Those are some of the reasons scam calls aren’t going away anytime soon.
“To be honest, it’s a global problem. … there’s no silver bullet,” said Alain Garneau, director of telecommunications enforcement at the CRTC, Canada’s telecom regulator.
The CRTC mandated that telecom companies start using STIR/SHAKEN in November 2021. “STIR/SHAKEN will undoubtedly reduce spoofing and help Canadians regain peace of mind when answering phone calls,” said then-CRTC chair Ian Scott.
But the technology isn’t foolproof. It doesn’t actually block calls, but instead, flags them as “likely fraud” or “likely spam.” It’s up to you to decide whether to pick up.
Also, it only works on calls made — from end to end — on upgraded phone networks that use internet-based systems. Phone companies are still upgrading their networks to these systems. So, at this point, the alerts come through on some calls and not on others.
“STIR/SHAKEN will become more effective over time,” as phone companies upgrade their systems, CRTC spokesperson Valérie Lavallée said in an email.
She was not able to say what percentage of calls are currently covered by STIR/SHAKEN.
CBC News asked the three major telecoms for data.
Bell said in an email that the number of calls on its network that STIR/SHAKEN can screen is “increasing constantly over time.”
Rogers said most of its calls are covered by the technology. Telus did not respond.
Buying a local number
Another hurdle, as with any crime-fighting technology, is that fraudsters eventually catch on.
“These scammers are financially motivated and driven,” said Toronto-based tech and cybersecurity expert Ritesh Kotak. “They do invest in research and development and figuring out ways to circumvent the system.”
He said scammers are able to bypass STIR/SHAKEN by purchasing and making calls from legitimate Canadian phone numbers — from anywhere in the world.
“It is extremely simple to get a local phone number. There are apps that are available,” he said. “There’s no location verification when a number is purchased. All you really need is a credit card.”
Garneau says the CRTC can’t stop scammers from making calls from valid phone numbers, but that some of Canada’s telecoms are fighting them head-on with their own technologies.
For example Bell has developed an artificial intelligence program that can detect a large number of robocalls made from a single number.
“They’re blocking real fraudulent activity that way,” Garneau said.
Telus and Rogers told CBC News they have also put in place programs for their customers that detect and block spam calls.
Despite the measures in place to combat phone scams, some people are still falling victim.
According to the the Canadian Anti-Fraud Centre, 1,973 people lost a total of $20.6 million to phone scams in the first three months of this year. The actual figure is likely much higher as not all victims report their case to the Centre.
Kotak says, along with new technologies, education is key in curbing this type of fraud.
“Scammers are going to be there as long as we’re making phone calls,” he said. “So it’s very important that we educate the population on what is a scam call, [and] ensure that it gets reported.”
Selvaraj agrees, which is why he recently recorded and posted a scam call on his YouTube channel. In the call, the fraudster tried to convince Selvaraj that a mysterious $1,534 had been charged to his Amazon account. He called out the scammer who quickly hung up.
Selvaraj’s channel caters to newcomers in Tamil community, so he hopes the video will warn them what to watch out for.
“It’s important to spread this awareness,” he said.
“I’ve been in Canada for the past 10 years. Sometimes, even I find it hard to know whether the call is legit or not.”
