How to Call Canada from the US: The Cheapest Options Explained
April 2, 2026 · 5 min read
Calling Canada from the US is often included in mobile plans — but not always. Here's when it costs extra, when browser-based calling saves money, and what to watch out for.
Canada looks close but calling can still cost you
The US and Canada are in the same NANP (North American Numbering Plan), which means Canadian numbers look exactly like US numbers — a 10-digit number starting with an area code. This leads many people to assume calls to Canada are the same as domestic calls. They're not, on most plans.
Many US carriers treat Canada as international calling, even though Canadian numbers don't have a different country code for everyday dialing purposes. Unless your plan explicitly includes Canada in your domestic allowance, you may be charged international rates — which range from $0.05 to $0.25 per minute depending on your carrier.
Which US carriers include Canada for free
T-Mobile Magenta and Magenta MAX plans include unlimited calling to Canada and Mexico at no extra charge. AT&T's International Day Pass (around $10/day) covers Canada when active. Verizon's Travel Pass also covers Canada. Many basic or prepaid US plans do not include Canada and charge standard international rates.
If you're unsure whether your plan includes Canada, check your carrier's international calling page or look at a recent bill where a Canada call appeared. Some plans include Canada in the fine print of 'North America calling' bundles; others charge per minute without warning.
When browser-based VoIP makes more sense
Browser-based calling to Canada costs around 1 cent per minute — lower than most carrier international rates and comparable to domestic US rates. If you're on a plan without Canada included, or you're currently traveling abroad and need to call a Canadian number without using your roaming plan, VoIP is straightforwardly cheaper.
OpenDial supports calls to Canadian landlines and mobiles. You dial using the Canadian number in standard format (country code +1 followed by the 10-digit number), and the call routes over your internet connection. There's no monthly fee or minimum balance.
Calling Canada from a third country
If you're traveling in Europe, Asia, or anywhere outside North America and need to call a Canadian number, your situation is the same as calling from the US — your home carrier's rates apply, and roaming makes them worse. Browser-based VoIP sidesteps this entirely.
Connect to local Wi-Fi, open OpenDial in your browser, and dial the Canadian number. The call goes over the internet at the same per-minute rate regardless of where you physically are. This is especially useful for people who travel frequently and need to reach Canadian contacts without tracking carrier rates across countries.
Canadian mobile vs. landline — any difference?
Unlike the UK, Canada doesn't have a separate pricing tier for calling mobiles vs. landlines from abroad. Both are charged at the same per-minute rate for international callers, because Canadian numbers don't distinguish mobile from landline in the number itself.
The 10-digit Canadian number format is identical regardless of whether it's a cell or a fixed line. This simplifies things: you don't need to check what kind of number you're calling before you dial.
The simplest path if you call Canada regularly
If you make calls to Canada more than a few times a month, the most cost-effective options are: upgrade to a plan that includes Canada (T-Mobile Magenta is the clearest choice), or use a pay-as-you-go VoIP service at around 1 cent per minute. Both are substantially cheaper than carrier international rates charged per call.
For truly occasional calls — once or twice a month — the math is simple: check what your current carrier charges, compare it to VoIP rates, and choose whichever is lower for your usage. Many people find that loading a small credit balance on a VoIP service covers their Canada calling needs for several months at a fraction of what their carrier would charge.
