Short answer: you do not need a copper landline to send a fax in Canada. A fax machine can work through a VoIP line and an analog telephone adapter (ATA), but reliability depends on the provider, the codec and settings like T.38. For occasional sends, an online service that dials the recipient for you avoids the equipment problem entirely.
FaxTelecom sends faxes from a web browser to landlines in seven countries, Canada included. It does not receive faxes and does not issue numbers.
Why is the landline disappearing in Canada?
Two trends overlap. Households increasingly rely on mobile phones alone and cancel their home line. At the same time, the large phone companies are rebuilding their networks around fibre, and in a growing number of areas the "home phone" they sell is no longer a copper circuit. It is a digital voice service carried over fibre or cable, delivered through a box in your home. The CRTC oversees this transition, and timelines vary by company and region. Our page on the copper switch-off and fax explains what changes for fax machines in general.
For most people this is invisible on a voice call. A fax machine notices, because fax was designed for an unbroken analog line.
What options do you have without a copper line?
| Option | What you need | Reliability for fax | Best for |
|---|---|---|---|
| Digital home phone from your internet provider | The provider's modem or voice box, and your fax machine | Often fine, but not guaranteed by every provider | Households that kept a home number |
| Third-party VoIP plus an ATA | A VoIP account, an ATA, your fax machine | Variable; best with T.38 support | Small offices with regular fax traffic |
| Online fax service (send only) | A browser and a PDF | No line-quality issues on your side | Occasional sends |
| Fax-to-email subscription | An account with a provider that issues a fax number | Depends on the provider | Receiving faxes |
| Library, print shop or shipping store | A trip and a fee | Fine | One-off documents on paper |
Why do faxes fail over VoIP?
Voice over IP compresses sound and sends it in packets. Your ear tolerates a tiny gap or a slight change in tone, but a fax modem reads every tone as data. Three problems come up most:
- Compression codecs. Codecs built for voice, like G.729, distort fax tones. G.711 passes them far better.
- Packet loss and jitter. A few lost packets can break the handshake or corrupt a page. That is why calls drop at page two.
- No T.38 at both ends. T.38 is a protocol made to carry fax over IP networks. When your ATA and your provider both support it, fax becomes far more reliable. When only one side does, results vary.
How do you set up a fax machine on VoIP?
If you want to keep a physical machine, these steps give it the best chance.
- Ask your provider directly whether it supports fax and T.38. Some providers state plainly that fax is not supported.
- Plug the fax machine into the voice port of the modem or ATA, not into a wall jack that may no longer be connected.
- Enable T.38 in the ATA settings if your provider supports it. Otherwise, force G.711.
- Lower the fax speed. Many machines have a setting to limit transmission to 9,600 or 14,400 bit/s. Slower is steadier over IP.
- Turn off error correction mode (ECM) only as a test if pages keep failing. On some lines it helps, on others it makes things worse.
- Send a test page to a friend or supplier whose machine is reliable, and ask whether it arrived clean.
Keep the ATA on a power bar with surge protection. If the router or ATA loses power, the line goes down with it, unlike the old copper line that drew power from the exchange.
When is online fax simpler?
If you send a few faxes a year (a form for a pharmacy, a document for a government office, a signed contract for a supplier), owning a machine and nursing a VoIP line is a lot of effort for little use. An online service puts the modem on its side: you upload a PDF, and its platform dials the recipient's fax machine over the phone network.
With FaxTelecom, there is no account and no software. You choose Canada, type the ten-digit number in national format, area code included, add your PDF (up to 100 MB) and confirm by email. A countdown of about 55 seconds lets you cancel, then the fax goes out and the status updates live. A one-page fax is free. Two pages or more cost €3.99 per send, whatever the page count. If you need proof, the PDF receipts option costs €2.99, billed only once delivery succeeds. The Canada destination page lists the number formats we accept. Fax machines answer on fixed lines; mobile numbers are out of reach.

What about receiving faxes without a landline?
Sending and receiving are separate problems. FaxTelecom only sends and does not issue numbers. To receive faxes, you need either a fax machine on a line that handles fax reliably, or a provider that assigns you a Canadian number and forwards incoming faxes to your inbox. Our page on receiving faxes goes through the options.
Where do you find the recipient's fax number?
On the recipient's own documents: a letter, a form, an invoice, an official website. For government offices, use the number printed on the correspondence you received rather than a number found online. Our guide on how to fax a public body gives the general method.
Quick questions
Do I need a landline to fax the CRA or a pharmacy? No. Any working fax path will do, including an online service.
Will my old fax machine work with my internet provider's home phone? Often, but not always. Send a test page before you depend on it.
Can I fax from my phone? Yes, from the phone's browser, as long as you have the document as a PDF. Start from the FaxTelecom home page.
