Is cable internet a good choice for my business?
Cable internet can work for a business, but in 2026, fibre is usually the better first choice if it is available at your exact address. Cable is still useful because it is widely available, installs quickly in many buildings, and delivers strong download speeds. The main weakness is upload speed.
Most cable business internet is still asymmetric, which means the download speed is much faster than the upload speed. That can be fine for browsing, email, and light cloud use, but it can become a problem for video calls, VoIP phones, cloud backups, large file uploads, and teams that work in shared cloud apps all day.
It is also worth correcting a common assumption. Fibre is expanding quickly in Canada, but it is not available at every business address. The CRTC reports that about 72% of Canadian households have access to fibre at home, while high-speed broadband coverage is much broader. Commercial buildings still need to be checked one by one because a street can have fibre nearby while an older building does not have it inside.
Quick answer: choose fibre if it is available for a similar price. Choose cable if fibre is not available, you need service installed quickly, your team is small, or you want cable as a backup to a fibre connection.

Let’s break down what cable internet actually delivers, where it falls short, and when it still makes sense for a business in Canada.
What Is Cable Internet in 2026?
Cable internet uses hybrid fibre-coaxial infrastructure, often called HFC. Fibre carries the signal through the provider’s main network to a neighbourhood node, and coaxial cable completes the connection from that node to homes or buildings. This is why cable internet is often called coax internet.
In Canada, the major cable internet providers include:
- Rogers, which now includes the former Shaw cable footprint after the Shaw acquisition closed in April 2023. Rogers is the main cable provider in many parts of Ontario, Atlantic Canada, British Columbia, Alberta, Saskatchewan, and Manitoba.
- Vidéotron, serving much of Quebec.
- Cogeco, serving parts of Ontario and Quebec.
- Eastlink, serving Atlantic Canada and some smaller regional markets.
Shaw no longer operates as a separate internet company. Rogers completed its acquisition of Shaw Communications in April 2023. If your business was previously on Shaw internet in Western Canada, you are now on Rogers, although the same local cable infrastructure may still be serving your building.
If you are comparing providers, it is also worth reading our guide to the best business internet providers in Canada. Cable may be the right fit in some buildings, but you should compare it with fibre, dedicated fibre, fixed wireless, and backup options before signing a contract.
The Upload Speed Problem
This is the biggest reason fibre is usually better than cable for business use.
Cable internet has traditionally been built around strong download speeds and much lower upload speeds. That made sense when most people mainly downloaded web pages, videos, and files. It is less ideal for modern businesses that send data back to the internet all day.
On current cable-style business plans, the headline download speed may look very fast, but the upload speed is often much lower. A plan may advertise hundreds of Mbps or more than 1 Gbps download, while upload may be much lower depending on the area, the plan, and the network upgrades available at that address.
Fibre-to-the-premises plans usually offer much stronger upload performance. For example, some Bell small business fibre plans list 300 Mbps download with 300 Mbps upload, while higher fibre tiers can offer far more upload than cable-style plans. Not every fibre plan is perfectly symmetrical at every speed tier, but fibre is still usually much better for upload-heavy work.
Why does this matter? Because many normal business tasks need upload speed:
- Video conferencing sends your video and audio upstream. A few calls are usually fine. A full team on Zoom or Microsoft Teams can quickly expose a weak upload connection.
- VoIP phone calls use both upload and download. Each call is small, but call quality can drop if the upload side is busy or unstable.
- Cloud file syncing with OneDrive, Google Drive, Dropbox, SharePoint, or similar apps needs upload speed when staff save and share files.
- Cloud backups are mostly upload. A slow upload connection can cause backups to run for hours and compete with staff during the workday.
- Large file transfers are common for design firms, construction companies, architects, engineers, accountants, healthcare offices, and media businesses.
The simple issue: if your cable plan has plenty of download speed but limited upload speed, your team may still feel like the internet is slow. The download side can be sitting mostly unused while video calls, file syncing, and cloud backups fight over the smaller upload pipe.
What Cable Internet Does Well
Cable has real strengths. It should not be dismissed completely, especially when fibre is not serviceable at your building.
Wide Availability
Cable is available in many urban and suburban business areas. In some older commercial buildings, cable may already be wired while fibre still needs construction. This can make cable the practical choice when you need service now.
Fast Installation
If coaxial cable is already in the building, installation can often be faster than fibre construction. Fibre can also be installed quickly if the building is already serviceable, but if new construction is required, the timeline can stretch from weeks to months.
Strong Download Speeds
Cable can deliver strong download performance. For browsing, software updates, downloading files, training videos, point-of-sale systems, guest Wi-Fi, and general office use, cable may feel fast enough for a small team.
Good Backup Option
Cable is often excellent as a backup connection. If your main internet is Bell or TELUS fibre, a Rogers cable backup can provide carrier diversity and technology diversity. That matters because a backup connection is more useful when it is not using the same provider and path as your primary connection.

Shorter Commitments in Some Cases
Cable business plans can sometimes be easier to set up on shorter terms than dedicated fibre. This can be useful for temporary offices, seasonal businesses, pop-up locations, or businesses that may move soon.
Usually Unlimited Data
Most mainstream business cable internet plans are sold with unlimited data. Still, always check the service agreement for fair-use terms, traffic management rules, and any contract-specific limits.
Cable vs Fibre: The Comparison That Matters
| Feature | Cable Business Internet | Business Fibre | Dedicated Fibre / DIA |
|---|---|---|---|
| Best use case | Small teams, download-heavy work, backup internet, buildings without fibre | Most offices, cloud apps, VoIP, video calls, growing teams | Mission-critical businesses that need guaranteed performance |
| Download speed | Often strong, with 1 Gbps+ available in some areas | Strong, often 300 Mbps to multi-gig depending on provider and location | Chosen by contract, often 100 Mbps to multi-gig |
| Upload speed | Usually much lower than download speed | Usually much stronger than cable; sometimes symmetrical depending on plan | Usually symmetrical |
| Performance consistency | Can vary by node, area, and upload congestion | Usually more consistent than cable | Most consistent |
| SLA with financial credits | Usually not the same as a dedicated internet SLA | May include business support, but not always a true DIA-style SLA | Yes, normally the main reason to buy it |
| Install timeline | Often fast if coax is already present | Fast if building is serviceable; longer if construction is needed | Can take weeks or months if construction is needed |
| Typical contract | Often flexible compared with dedicated fibre | Often better pricing on 2 or 3 year terms | Usually contract-based |
| Best fit | Budget-conscious or backup connection | Best default choice for most small and medium businesses | Businesses that cannot tolerate downtime or inconsistent speed |
Do not compare only the download number. A 1 Gbps cable plan with limited upload can be worse for a busy office than a 300/300 fibre plan. For business use, upload speed, reliability, support, contract terms, and backup options matter more than the biggest advertised download number.
DOCSIS 4.0: Will Cable Close the Gap?
DOCSIS 4.0 is the cable industry’s next major upgrade. It is designed to make cable networks faster and improve upload performance. This matters because upload speed is the main reason cable loses to fibre for business use.
Rogers announced a partnership with Comcast in 2024 to use Comcast’s access network architecture and support next-generation internet services in Canada. Rogers has also reported DOCSIS 4.0 trial results with multi-gig download and much higher upload speeds than older cable service.
That is promising, but it does not mean every business can order DOCSIS 4.0 today. Availability depends on your city, neighbourhood, local node, modem, and whether the required network upgrades have been completed at your address.
- Good news: cable upload speeds should improve over time as Rogers and other cable providers upgrade their networks.
- Important caution: do not choose a business plan today based on a future upgrade that is not available at your building yet.
- Best question to ask: “What exact upload speed is available at my business address today?”
Our take: DOCSIS 4.0 could make cable more competitive with fibre in the future. But if fibre is already available at your address for a similar price, choose the fibre plan now rather than waiting for cable to catch up.
When Cable Makes Sense for a Business
Cable is not the best option for every business, but there are still several situations where it makes sense.
Fibre is not available at your address. This is the most common reason to choose cable. Even in large Canadian cities, some older commercial buildings do not have fibre inside. If cable is the best wired option available, it can be a reasonable choice.
You need internet quickly. If you are opening a new office, retail store, clinic, or temporary location, cable may be installable faster than fibre construction.
Your team is small. A team of 1 to 5 people that mainly browses, emails, downloads files, and uses light cloud apps may be fine on cable.
You do not rely heavily on VoIP or cloud backups. Cable is more likely to work well when upload-heavy tools are not central to your daily operations.
You need a backup internet connection. Cable can be a smart backup to a fibre connection. This is one of the strongest use cases for business cable internet.
You are in a temporary space. If you may move soon, a shorter cable commitment can be easier than a longer fibre or dedicated internet contract.
When Cable Is Not Enough
You should usually choose fibre over cable if any of these apply to your business:
- You have more than 5 employees on video calls regularly. The upload side can become the bottleneck.
- You use VoIP phones. VoIP needs low latency, low jitter, and enough upload capacity.
- You rely on cloud apps all day. SharePoint, Google Workspace, Microsoft 365, QuickBooks Online, Salesforce, cloud POS systems, and cloud backups all benefit from stronger upload.
- You upload large files. Creative, architecture, engineering, construction, accounting, legal, and healthcare businesses often need stronger upload than cable provides.
- You need a true SLA. If downtime costs money, look at fibre or dedicated internet access instead of standard cable.
- You need predictable performance. Fibre, especially dedicated fibre, is usually better for businesses that cannot tolerate slowdowns.
If guaranteed uptime and performance are important, read our guide on what a leased line costs. Dedicated internet is more expensive than regular cable or business fibre, but it exists for businesses that need stronger guarantees.
Questions to Ask Before Choosing Cable
If you are considering cable internet for your business, ask these questions before you sign:
- What is the exact upload speed? Do not rely only on the headline download speed.
- Is fibre available at this exact business address? Check Bell, TELUS, Rogers fibre where available, regional fibre companies, and local business providers.
- Is the plan cable, fibre-to-the-premises, or dedicated fibre? Providers sometimes use similar marketing language for very different technologies.
- Is there a real SLA? Ask whether there are financial credits, guaranteed repair times, and written uptime commitments.
- Can I get a static IP? Many businesses need this for VPNs, servers, cameras, or remote access.
- What are the contract terms? Confirm the term length, installation fees, renewal pricing, and early cancellation fees.
- What backup option should I use? If the business depends on internet, do not rely on one connection only. Consider fibre plus cable, cable plus LTE/5G, or fibre plus Starlink depending on your location.

Business Internet CalculatorFrequently Asked Questions
Is cable internet good enough for a small business?
Yes, cable can be good enough for a small business if the team is small and the work is not upload-heavy. It is usually fine for browsing, email, light cloud use, guest Wi-Fi, and occasional video calls. Fibre is still the better choice if it is available for a similar price.
Why is cable upload speed slower than download?
Most cable internet networks were built to deliver much more downstream capacity than upstream capacity. That worked well when people mostly downloaded content. It is less ideal for modern business work, where video calls, file sharing, cloud backups, and collaboration tools all need upload speed.
What happened to Shaw business internet?
Shaw Communications was acquired by Rogers, and the merger closed in April 2023. Former Shaw internet customers in Western Canada are now part of Rogers. In many areas, the local cable infrastructure is the same, but billing, support, branding, and future upgrades are now under Rogers.
When will DOCSIS 4.0 be available for my business?
Availability is address-specific. Rogers has announced next-generation cable network plans and has tested DOCSIS 4.0 technology, but businesses should not assume it is available everywhere. Ask the provider what upload speed and modem are available at your exact address today.
Can I use cable as a backup connection?
Yes. Cable is often a very good backup connection if your main service is fibre from a different provider. For example, a Bell fibre primary connection with a Rogers cable backup can provide better diversity than buying two services from the same provider. You will also need a router or firewall that supports automatic failover.
Does cable business internet have data caps?
Most mainstream business cable internet plans are marketed as unlimited. Still, confirm the plan details before signing, especially if your business moves a lot of data or uses cloud backups. For more details, read our business internet data caps guide.
Should I choose cable or fibre for business internet?
Choose fibre if it is available for a similar price. Choose cable if fibre is not available, you need a fast install, your team is small, or you want a backup connection on a different network. If your business uses VoIP, video calls, cloud backups, or large file uploads, fibre is usually the safer choice.
