How to Get a Business Phone Number in Canada
Learn how to get a business phone number in Canada today — landline, mobile, VoIP and virtual options, plus record-keeping tips for sole proprietors.
Getting a business phone number in Canada today usually means choosing among three routes: a traditional landline from a telecom carrier, a dedicated mobile line, or a hosted VoIP cloud business phone system that gives you a virtual phone number in Canada. None of these requires a separate phone licence from the CRA. What matters is that the number is used consistently for your business, listed in your customer-facing materials, and that any related expenses are recorded properly if you claim them as a sole proprietor.
What Counts as a Business Phone Number?
A business number in the phone sense is simply a telephone number you use primarily for commercial activity: taking client calls, booking appointments, providing support, or receiving texts and faxes from customers. It can be a local number with a Canadian area code, a toll-free number, or a mobile line kept separate from your personal phone.
Don't confuse it with your Business Number (BN). A BN is the identifier the CRA issues for programs such as GST/HST, payroll deductions, and corporate income tax. A phone number comes from a telecom or VoIP provider, not from the CRA. A sole proprietorship can hold a business phone number without having a BN if it is not registered for any CRA program, although most owners eventually obtain one.
Do You Need to Register a Business Before Getting a Phone Number?
Not usually. Canadian carriers and VoIP providers sell business accounts to sole proprietors, partnerships, and corporations. Some ask for a legal business name, a registration number, or proof of address, while others will set up an account under your own name and simply label the line as business.
If you operate under a registered trade name, that name will often appear on your carrier account. If you operate under your own legal name, the account will use your personal name. See whether you need to register a sole proprietorship and business name vs operating name for the naming rules.
Types of Business Phone Systems Available
Most Canadian small businesses choose from the options below. Availability of specific features and contract terms varies by provider, so confirm details directly.
| Option | How it works | Typical fit |
|---|---|---|
| Traditional landline | Physical line installed by a telecom carrier | Fixed locations needing a reliable line |
| Dedicated mobile line | A second SIM or plan used only for work | Mobile trades, consultants, on-site services |
| VoIP / hosted PBX | Calls routed over the internet to an app or desk phone | Teams needing extensions, menus, call routing |
| Virtual phone number in Canada | A number that forwards to any device, with no physical line | Home-based and remote businesses |
| Toll-free number | A 1-800-style number customers call at no charge | National sales or support lines |
Steps to Set Up a Business Phone Number
- Decide whether you need a local number, a toll-free number, or both.
- Choose a provider — a national carrier, a regional telecom, or a VoIP service.
- Gather your legal name, business address, and, if requested, your BN or registration number.
- Select a plan and confirm contract length, per-user pricing, and number portability terms.
- Complete verification, then configure voicemail, call forwarding, and business hours.
- Publish the number consistently on your website, invoices, email signature, and directory listings.
What Does a Business Phone System Cost?
Pricing varies significantly by provider, feature set, and number of users. Hosted VoIP plans are usually billed per user per month, while landlines and mobile plans can involve hardware, installation, or longer contracts. Toll-free numbers may carry per-minute usage charges. Confirm current rates, setup charges, and cancellation terms with each provider before signing.
For tax purposes, the CRA does not charge a fee for having a phone number. If you claim a portion of a phone bill as a business expense, the deduction must reflect actual business use. Keep monthly statements and a reasonable record of how you calculated the business share — see bookkeeping for sole proprietors.
Keeping Phone Records and Separating Business Use
If a phone line is used for both personal and business calls, only the business portion is generally deductible. A common approach is to keep a separate business line, or to document the percentage of business use and apply it consistently. Statements should be retained with your other business records; see business records retention in Canada for how long to keep them.
Your business number should also appear in the right places on customer documents. If you invoice clients, the number belongs in the header along with your name, contact details, and GST/HST information where applicable — see how to invoice as a sole proprietor.
Mistakes to Avoid
- Using a personal mobile number everywhere and then being unable to separate business use later.
- Forgetting to update the number on invoices, contracts, and online listings after a change.
- Assuming a virtual number behaves identically to a landline for emergency calls — confirm 911 and service limitations with the provider.
- Signing a long contract before checking whether the number can be ported if you switch providers.
A consistent business phone number supports credibility, and pairing it with a matching email address keeps your brand coherent — see business email and domain setup.
Frequently asked questions
Do I need a Business Number to get a business phone number in Canada?
Generally no. Carriers and VoIP providers sell business lines to sole proprietors without a CRA Business Number. Some may ask for a registration number or business name when setting up the account, but a phone number is a telecom service, not a CRA program. You would need a BN separately if you register for GST/HST or payroll deductions. Confirm the provider's requirements when you sign up.
What is the difference between a business phone system and a virtual phone number?
A business phone system is the overall setup — handsets, apps, call routing, extensions, and voicemail. A virtual phone number, sometimes called a VoIP or cloud number, is a specific number not tied to a physical line that forwards calls over the internet. Many Canadian providers bundle virtual numbers into a hosted phone system, so you can add features without installing wiring.
Can I use my personal cell phone as a business phone number?
You can, but it blurs personal and business use. For tax purposes, you would generally deduct only the business-use portion of the bill and need records to support it. Many sole proprietors add a second line or a virtual number that forwards to their cell instead, which keeps call logs and voicemail separate. Ask an accountant how to treat the expense in your situation.
Is a toll-free number worth it for a Canadian small business?
It depends on your customers. A toll-free number can help if you serve clients across multiple provinces or want a single national contact point, and some VoIP providers include one with a plan. However, toll-free lines may carry per-minute usage charges and do not replace a local number for local search visibility. Review provider terms before committing.
