Living in Canada , almost everyone has experienced this: your cell phone suddenly rings, and the screen displays a number you’ve never seen before. Sometimes it’s a local area code like 416, 647, 604, 778, or 289, and sometimes it’s from the United States or even Europe. When you answer, no one speaks; if you don’t answer, it rings once and then hangs up; you just blocked a number, and soon another one calls. Recently, there has been a noticeable increase in similar calls from unknown numbers across Canada. On Reddit’s r/askTO community, a user said that he had received more than 40 spam calls in a week starting from Monday, including 11 by noon on just one day. “We stop one, then replace them; we can’t stop them all.”
What’s even more puzzling is that some of the incoming calls are very similar to my phone number, sometimes only the last few digits are different, making them seem like they’re from someone nearby. However, the fact that the caller ID shows a local number does not mean that the call actually came from the local area. Scammers and automated dialling systems can use caller ID spoofing to make the phone number appear as a Canadian area code such as 416, 604, 647, or 778, or even deliberately disguise it as a number very similar to yours. Therefore, manually blocking each and every unknown caller is often not the most effective solution when faced with a constant stream of calls from strangers. If you are also frequently harassed by these kinds of phone calls in Canada, you can try the following methods. First tip: Don’t rush to answer unfamiliar numbers, and definitely don’t call back casually.
The simplest method is often the most effective step.
If you don’t have an important call waiting for you, you can put the number into voicemail first. When people actually need help from hospitals, schools, banks, repairmen, or other organizations, they usually leave their information or contact you again. Especially for calls that ring only once and then hang up, don’t call back out of curiosity. Some spam and scam calls are made by using automated dialling systems to test phone numbers in batches, looking for numbers that can be reached and that are in use. Therefore, it is not necessary to verify every number you do not recognize. At the same time, do not assume that the other party is trustworthy just because the screen displays familiar local area codes such as 604, 778, 416, 647. The second trick: Turn on the built-in unknown caller filter on your phone.
Many people already have anti-harassment features on their phones, but they just haven’t turned them on. iPhones can use features such as silencing unknown calls. Once enabled, unfamiliar numbers that don’t appear in your contacts or recent contact history can be muted and transferred to voicemail, preventing them from interrupting you every time. This method is very effective for a large number of automated dialling calls. However, the drawbacks are also obvious: normal calls from hospitals, schools, delivery companies, repair companies, etc., may use phone numbers that you haven’t saved. If you are waiting for a call from a doctor, school, or other important institution, you should be a little more cautious. Android and Google Pixel
Some Android phones also offer spam call identification and filtering features. Google Pixel’s Call Screen feature is more proactive. When an unknown number calls, the system can first ask who the caller is and why they are calling, and then decide whether to answer based on their response. For automated dialling robots, this step alone can block a significant number of calls, while real doctors, repairmen, or other human callers can still explain their purpose. Therefore, if you receive a lot of calls from unknown numbers, first check your phone’s “Phone” or “Incoming Calls” settings; there may already be free tools available. Third tip: Check if your mobile carrier offers a free anti-harassment feature.
In addition to the phones themselves, Canadian carriers also offer various forms of spam call filtering. Among them, the Call Controls provided by Telus and Koodo are quite practical . Once enabled, some first-time callers to your number will need to listen to system prompts and press specific numbers before the call can be connected. For a real person, this process only takes a few seconds; but many automated dialling bots cannot complete this step and are therefore blocked. If you receive a large number of bot calls every day, this method is often much more effective than constantly blocking the numbers. Rogers and Fido offer features to identify spam and scam calls.
Some suspicious numbers may be marked as “Likely Spam” or “Likely Fraud” when they call, reminding users to be cautious when answering. Operators such as Bell and Virgin Plus also have different forms of network-level spam and scam call filtering mechanisms. Therefore, if you suddenly start receiving a lot of calls from unknown numbers every day, you can first log into your carrier account or check your phone settings to see if there is a free anti-harassment service that you can activate.
Fourth strategy: If that still doesn’t work, then consider a third-party app.
If the features provided by your phone and carrier are still insufficient, you can also consider third-party call filtering tools. For example, Truecaller, Call Control, RoboKiller, and Nomorobo all offer varying degrees of spam call identification, automatic blocking, or call filtering capabilities. These types of apps typically rely on a database of phone numbers and user reports to determine whether a number is suspicious. However, it’s not true that the more third-party apps you install, the better. Some features require a paid subscription, and some caller ID software may request permissions related to the address book, contacts, or phone numbers. Before installation, it’s best to carefully review the pricing and privacy policy. For most people, a simpler order is: First, enable the phone’s built-in filters → then enable the carrier’s free services → if that’s still not enough, then consider third-party apps.
Be especially wary if the other party claims to be from a bank, CRA, or police. The most troublesome thing about spam calls is not just the harassment. Some calls go further and impersonate agencies such as banks, the Canada Revenue Agency (CRA), police, courier companies, telecommunications companies, and even the Canada Border Services Agency. At this point, no matter how “legitimate” the caller ID looks, do not believe the other party’s identity based solely on the phone number.
You should be especially wary if the other party asks you to provide your bank account, online banking password, SMS verification code, SIN, or requests to transfer money, purchase gift cards, or transfer cryptocurrency. The safest way is not to continue verifying with the other party over the phone, but to hang up, find the phone number published on the organization’s official website, and then call back to confirm. The same applies to banks. Even if the caller ID shows your bank’s phone number, it doesn’t completely prove the call actually came from your bank, as the caller ID could also be spoofed. Don’t block them one by one; the key is to prevent bots from calling.
Many people’s first reaction to spam calls is to keep adding the number to their blacklist. This might be acceptable for a few numbers occasionally, but if you receive seven, eight, or even a dozen different numbers in a day, it’s not very meaningful to keep blocking them one by one. Because automated dialling systems can constantly change numbers, and scammers can also forge numbers that don’t belong to them at all. The truly effective method is to make the most of the automatic filtering mechanisms provided by mobile phones and carriers, so that a large number of robocalls are blocked before they actually ring your phone.
So, if you’ve recently started receiving frequent calls from unknown numbers, remember a few principles: Don’t rush to answer or call back unfamiliar numbers; local area codes don’t guarantee safety; use your phone’s filtering function first, then use your carrier’s anti-harassment feature; when dealing with sensitive identities such as banks, CRAs, or police, hang up and verify through official channels yourself. While doing these things may not completely eliminate spam calls, it will at least significantly reduce the number of unknown numbers ringing every day and greatly decrease the risk of falling into a phone scam trap.
