Cheapest Way to Call Canada from the UK: 6 Options Compared

Calling Canada from the UK costs as little as £0.02 per minute in 2026 — but most people are still paying 10 to 20 times that through their mobile carrier without realising it. UK networks routinely charge £0.30–£0.60 per minute for international calls to Canada, even with bolt-ons. This article breaks down six real options: what they cost, where the hidden fees are, and which one makes sense for your situation. We've done the maths so you don't have to.

Key Takeaways:

• Browser-based VoIP (like GlobCall) reaches Canadian numbers for as little as $0.02/min — that's roughly 2p per minute with no monthly fee or app download required.
• WhatsApp and FaceTime are genuinely free but only work if the person you're calling is also online and has the same app — they won't reach regular Canadian phone numbers.
• UK carrier add-ons (EE, O2, Vodafone) typically cost £5–£10/month extra and still charge per-minute rates above 2p — often making them worse value than pay-as-you-go VoIP for light users.

What Does It Actually Cost to Call Canada from the UK Right Now?

Standard UK carrier rates to Canada in 2026 range from around £0.30 to £0.60 per minute before any add-ons. Even with an international bolt-on, you're often looking at £0.05–£0.15 per minute depending on your network. A 30-minute call to a Canadian mobile once a week adds up fast — sometimes over £50/month in call costs alone.

The UK–Canada route is one of the more manageable international corridors because Canada's country code (+1) shares infrastructure with the US. That's why VoIP rates to Canada are so low. The same $0.02/min rate that applies to US calls on most VoIP platforms typically applies to Canadian numbers too. Compare that to calling Nigeria or the Philippines and the difference is stark.

"Cheap" means different things depending on how you call. A free app with a monthly subscription might beat VoIP if you call for hours every week. A pay-as-you-go service suits occasional callers better. And some options that advertise as free have costs that aren't obvious until you're already signed up.

Option 1: Browser-Based VoIP (GlobCall)

GlobCall reaches any Canadian phone number — mobile or landline — for $0.02 per minute, with no monthly fee, no app to install, and no SIM card required. Open a browser tab, top up a balance, and call.

At $0.02/min, a 30-minute call to Canada costs about $0.60. Even accounting for the exchange rate, that's well under £0.50 for half an hour of talk time. No subscription, no seat fees, no per-user charges if you're a business sharing the account across a team.

GlobCall works in Chrome, Firefox, Safari, or whatever browser you're using, which means it runs on any device with a microphone and an internet connection. You top up what you need and pay only for what you use. For UK callers who ring Canada occasionally, this is usually the most cost-effective option available. You can check all destination rates on the rates page before spending anything.

There's also a free 60-minute trial call if you'd like to test call quality before committing. That's 60 real minutes to any supported number.

The one genuine drawback is connection dependency. A shaky Wi-Fi signal will affect call quality. On solid broadband or 4G/5G, though, the audio is comparable to a regular phone call.

Option 2: WhatsApp Calls

WhatsApp calls to Canada are free — provided the person you're calling has WhatsApp installed and is reachable on it. You can't use WhatsApp to dial a regular Canadian phone number. Both people need the app open and connected to the internet.

That's a real constraint. Calling a Canadian business, a landline, or someone who doesn't use WhatsApp simply won't work this way. But for keeping in touch with family or friends already on the platform, it's hard to argue with free.

Call quality on WhatsApp is generally solid over Wi-Fi or a good mobile connection. It's end-to-end encrypted, and in 2026 WhatsApp remains widely used globally, so there's a reasonable chance your contact already has it.

Reliability is the variable. WhatsApp calls can degrade noticeably over slower connections, and quality depends on both ends of the line. If your Canadian contact is on a weak rural connection, you'll hear it.

If you're weighing WhatsApp against other free options, this breakdown of free vs paid international calling apps is worth a look before deciding.

Option 3: FaceTime and iMessage Calling (Apple Users Only)

FaceTime Audio calls to Canada are free over Wi-Fi or mobile data, with no per-minute charge and no setup required — as long as both people are on Apple devices. iPhone to iPhone, this is a genuine zero-cost option.

The Apple-only requirement is the hard limit. Android users can't use it at all. Even among iPhone users, the person you're calling needs an active Apple ID and internet access at the time of the call.

FaceTime Audio quality is excellent. Apple's codec handles calls well even on moderate connections, and for one-on-one personal calls, the audio is hard to fault. The problem arises when your Canadian contact isn't on an iPhone — a landline, an Android mobile, a business number. That's when you need something else.

Option 4: Google Voice

Google Voice offers calls to Canadian numbers, but the situation in 2026 is more complicated than most articles let on. It's primarily designed for US-based users. Setting up a Google Voice account without a US phone number is genuinely difficult — you need a US number to verify the account, which most UK residents don't have.

If you've already got a Google Voice account set up (say, from a previous US stay), calls to Canadian numbers cost around $0.01/min — slightly cheaper than GlobCall on paper. But the setup friction for UK users without an existing account is significant enough that most people will find simpler services easier.

Google Voice is also increasingly positioned as a business communications tool rather than a consumer calling app. The free consumer tier still exists, but features are limited and support is minimal. The GlobCall vs Google Voice comparison gives a fuller picture of where it fits for UK callers.

If you already have Google Voice and it's working, it's a fine option for Canada. If you don't, the setup process probably isn't worth it.

Option 5: Rebtel

Rebtel is a calling app that's been around for years and offers international calls at low per-minute rates, including to Canada. In 2026, Rebtel's rates to Canadian numbers sit around $0.01–$0.02/min depending on whether it's a mobile or landline.

The fee structure is where it gets complicated. There's typically a connection fee per call (around $0.49), which makes short calls expensive. A 2-minute call with a $0.49 connection fee on top of $0.04 in actual call cost is a poor deal. The economics only improve for calls running 20 minutes or longer, where the connection fee gets spread across more minutes.

Rebtel also requires app installation and a registered account — you can't just open a browser tab and dial. For business users calling from multiple devices, that's an unnecessary friction point.

The GlobCall vs Rebtel comparison goes into more detail on the fee structures. The short version: Rebtel can work for long personal calls but doesn't suit short or irregular call patterns.

Option 6: UK Carrier International Add-Ons (EE, O2, Vodafone, Three)

UK carriers sell international calling add-ons, and Canada appears in almost all of them. The general structure in 2026: pay £5–£15/month extra and get either a bundle of international minutes or a reduced per-minute rate to specified countries.

EE's international add-on, for example, offers around 100 international minutes per month for roughly £10. Use all 100 minutes to Canada and that works out to 10p per minute — which sounds reasonable until you compare it to VoIP at 2p. O2 and Vodafone have similar structures with similar economics.

The case for a carrier add-on is convenience. You're using your existing phone number, your normal phone app, your existing data plan. No new accounts, no top-ups, no extra browser tabs. If you make a high volume of international calls to multiple countries and want a single bill, an add-on makes sense.

For UK-to-Canada specifically, the numbers rarely favour the carrier. Unless you're also calling other countries covered by the same add-on, you're overpaying. A broader comparison of UK international calling options helps clarify whether a carrier plan justifies its cost for your usage.

One thing worth checking: most carrier add-ons apply to calls made from the UK. If you're roaming abroad and want to call Canada, the rates change again — typically for the worse.

Which Option Is Right for You?

The answer comes down to three things: how often you call, whether you're calling a real phone number, and whether you want a monthly commitment.

If you call Canada regularly and need to reach actual phone numbers (mobiles, landlines, businesses), browser-based VoIP gives you the best rate with no strings attached. At $0.02/min, you'd need to make over 250 minutes of calls per month before a carrier add-on at £10/month would be cheaper — that's more than four hours of calls monthly, assuming the add-on covers your usage exactly.

If you only call one or two people in Canada who are already on WhatsApp or FaceTime, use those apps. No reason to pay for something a free option covers perfectly well.

For businesses calling Canadian clients or suppliers, the calculation shifts. You might want a Canadian local number that clients can call back. GlobCall's business features let you get local numbers in 100+ countries, share a balance across your team, and add unlimited users without per-seat charges — which matters when multiple people are making calls.

For a broader view of cheapest international calling options across different situations, the FAQ covers more ground.

Frequently Asked Questions

Can I call a Canadian mobile number from the UK cheaply, or is it more expensive than calling a landline?

Canadian mobile numbers cost the same as landlines on most VoIP platforms — $0.02/min on GlobCall applies to both. UK carrier rates sometimes differentiate, but the gap is usually small. The bigger cost difference is between VoIP and carrier calls, not between mobile and landline within Canada.

Do I need to dial a prefix to call Canada from the UK?

Yes. From the UK, dial 001 followed by the 10-digit Canadian number (area code plus number). On VoIP platforms like GlobCall, you typically enter the number in E.164 format: +1 followed by the 10-digit number. Most platforms handle this automatically if you select Canada as the destination.

Is the call quality on browser VoIP good enough for business calls?

On a stable broadband or 4G/5G connection, browser VoIP quality is comparable to a regular phone call — clear audio, no noticeable delay. Problems arise on weak or congested connections. For business calls where audio clarity matters, quality is consistently reliable on a decent internet connection.

What happened to Skype — can I still use it to call Canada?

Skype was shut down in May 2025 and its users migrated to Microsoft Teams. It's no longer available as a standalone service. If you were using Skype to call Canadian numbers cheaply, you'll need a replacement. The best Skype alternatives after the shutdown covers the current options in detail.

Does GlobCall work if I'm travelling abroad and want to call Canada?

Yes. GlobCall uses your internet connection rather than a SIM, so it works from any country with Wi-Fi or mobile data. No roaming charges, no carrier involvement. You can call Canadian numbers from Spain, Thailand, or anywhere else at the same $0.02/min rate.

The Bottom Line

Here's where each option stands:

• Lowest per-minute rate for real phone numbers: Browser VoIP (GlobCall at $0.02/min, roughly 2p) — no app, no subscription, no commitment
• Truly free option: WhatsApp or FaceTime, but only if both parties are on the same platform and online
• Best for convenience without a separate service: UK carrier add-on, but expect to pay 5–7x more per minute than VoIP
• Best for existing Google Voice users: Google Voice at ~$0.01/min, if you've already got the setup sorted
• Watch out for connection fees: Rebtel looks cheap per-minute but adds a per-call fee that hurts short calls
• Skype is gone: It shut down in May 2025 — you need a working alternative

To test the cheapest option before committing to anything, start with a free 60-minute call on GlobCall — no credit card required, no app to install. Open a browser tab and dial.
