The short answer
Take the .ca if you serve Canadian customers and you qualify - and you may not, because CIRA gates .ca behind Canadian Presence Requirements. Take the .com as well when it is free, and redirect it. Two registrations cost a few dollars a month and remove the guess entirely.
This is the first real decision most Canadian small business owners make about their website, and it usually gets made in about ninety seconds at a registrar checkout. That is a shame, because two facts sit underneath it that almost nobody knows, and both of them can cost you a rebrand later.
The first is that a .ca is not a product you can simply buy. It is a gated registry with a written eligibility test, and businesses fail it. The second is that neither ending protects you from the far more expensive mistake: choosing a name somebody else already owns as a trademark.
The gate: Canadian Presence Requirements
The Canadian Internet Registration Authority runs the .ca registry, and its policy states plainly that on or after November 8, 2000, only the individuals and entities it lists are permitted to apply for, hold, or maintain the registration of a .ca domain name [1]. The stated reason is that after public consultation, CIRA determined the .ca space should be developed as a key public resource for the social and economic development of all Canadians [1].
There is nothing comparable standing between anybody in the world and a .com. That single asymmetry is the whole reason a .ca carries a different signal, and it is also the reason some businesses discover, mid-launch, that they cannot have one.
The qualifying categories run to eighteen items. The ones that matter for a typical small business are these. A Canadian citizen at the age of majority under the laws of the province or territory where they reside or last resided. A permanent resident as defined in the Immigration and Refugee Protection Act who is ordinarily resident in Canada and at the age of majority. A corporation under the laws of Canada or of any province or territory. There are also categories for trusts and partnerships, which qualify when more than 66.6% of trustees or partners meet one of the earlier conditions, and for unincorporated associations, which need at least 80% of members and 80% of directors and officers ordinarily resident in Canada [1].
Beyond that the list covers trade unions with a head office in Canada, registered political parties, educational institutions, libraries, archives and museums, hospitals, Indian bands as defined in the Indian Act, Inuit, First Nation, Métis and other Indigenous peoples and collectivities, and governments at every level [1].
The residency test is not a box you tick once. CIRA defines "ordinarily resident in Canada" as an individual who resides in Canada for more than 183 days in the twelve-month period immediately preceding the application, and in each twelve-month period thereafter for the duration of the registration [1]. If you are a sole proprietor who spends more than half the year outside Canada, read that sentence twice.
The trademark back door
One category deserves separate attention because it is the route most foreign businesses end up using. A person who meets none of the other conditions, but who owns a trademark that is the subject of a registration under the Trademarks Act, may register a .ca - but only a domain consisting of or including the exact word component of that registered trademark [1]. A parallel provision covers official marks published under subsection 9(1) of the same Act [1].
So the door is narrow and shaped exactly like your registered mark. If you own a Canadian registration for NORTHFIELD, that gets you northfield.ca. It does not get you northfieldsupply.ca as a free-standing brand. In practice, the cleaner path for a foreign-owned operation selling into Canada is a Canadian incorporation, which qualifies on its own footing.
What each ending actually signals
Because .ca has an eligibility gate and .com does not, the .ca carries information a .com structurally cannot: whoever holds it made a declaration of Canadian presence to a registry. CIRA leans on this in its own marketing, describing .CA as Canada's trusted domain and citing 2025 research by the Strategic Counsel in which 87% of Canadians said .CA is best over .com for proudly Canadian businesses [2]. Treat that figure with the caution any registry's own promotional research deserves - but the underlying mechanism is real, and it is not a matter of opinion.
A .com signals something different and equally useful: scale, and the absence of a border. If you sell to the United States, or your product ships worldwide, or you might one day, the .com never has to be explained. It is also the ending people type by reflex when they half-remember a name, which is a practical fact about human behaviour rather than a branding theory.
The signal matters because the audience is effectively everyone. Internet use among Canadians aged 15 and over reached 95% in 2022, up from 92% in 2020 [7], and by 2020 more than four in five Canadians (82%) shopped online, with online spending of roughly $84.4 billion [8]. Your domain is the shortest piece of copy your business will ever write, and nearly every customer sees it.
Trust is also not abstract here. In 2022, 22% of Canadians reported being redirected to fraudulent websites asking for personal information [7]. Customers are pattern-matching on addresses whether or not they can articulate why, and an address that matches your business name and your country is the cheapest reassurance available.
The boring answer that is usually right: own both
Register both endings, serve the website from one, and redirect the other. Pick the one that matches your primary market as the canonical address - the one on your business cards, your invoices and your vehicle - and make the other a permanent redirect to it. Your customers stop being able to guess wrong, and nobody else can quietly buy the twin of your brand.
The cost of the second registration is trivial next to the cost of not having it, which is a competitor or a domain speculator owning the address half your customers will type. This is not a sophisticated strategy. It is closer to buying a second key for the shop.
The honest concession: when you should not bother
If your entire customer base is inside a fifteen-kilometre radius and always will be - a barber, a mobile mechanic, a snow-clearing route - the .com is doing nothing for you. Buy the .ca, skip the .com, and put the saved money into anything else. Similarly, if the .com is already owned by an unrelated business with a legitimate claim to the name, do not chase it. Paying four figures to a domain broker for a marginal typo-defence is a bad trade for a business at your stage, and a distinctive .ca that you actually own beats a compromise .com you rent attention on.
And if the .ca is taken but the .com is free while you serve only Canadians, take the .com and move on. The suffix is a signal, not a strategy.
The mistake that actually costs money
Domain availability tells you nothing about whether you are allowed to use a name. These are separate systems. A domain can be free to register while the name itself belongs to somebody else.
Under the Trademarks Act, registration of a trademark in respect of goods or services gives the owner the exclusive right to the use throughout Canada of that trademark in respect of those goods or services, unless the registration is shown to be invalid [4]. Section 20 deems that right infringed by a person not entitled to use the mark who sells, distributes or advertises goods or services in association with a confusing trademark or trade name [4]. Section 22 adds a separate hook: no person shall use a trademark registered by another in a manner likely to have the effect of depreciating the value of the goodwill attaching to it [4].
Unregistered rights exist too. Section 7 prohibits directing public attention to your goods, services or business in a way likely to cause confusion in Canada with those of another person - the statutory form of passing off [4]. The Canadian Intellectual Property Office puts the trade-off plainly: you do not have to register, and using a mark over time may give you common-law rights, but if you rely on an unregistered mark and end up in a dispute you could be facing a long, expensive legal battle over who has the right to use it [5]. Registration gives the sole right to use the mark across Canada for ten years, renewable [5].
CIPO also draws a distinction owners routinely miss: your trade name is the name of your business, and it can be registered under the Act only if it is also used as a trademark - that is, used to identify goods or services [5]. Registering a corporate name at the provincial or federal level is not a trademark clearance, and it is not permission to use that name in the market.
The domain itself is a representation
Here is the provision nobody expects. The Competition Act defines a locator as a name or information used to identify a source of data on a computer system, and expressly includes a URL [6]. Section 52.01 makes it an offence to knowingly or recklessly make a false or misleading representation in a locator for the purpose of promoting a business interest or the supply of a product, and section 74.011 makes the same conduct reviewable [6]. Section 52 also directs that the general impression conveyed by a representation, as well as its literal meaning, be taken into account [6].
Read that against a domain like certified-halifax-electricians.ca chosen by someone who is neither certified nor in Halifax. The general impression is the whole point of the name, and the Act says the general impression counts. Pick a domain that describes what you truly are.
How a .ca can be taken from you
CIRA's Domain Name Dispute Resolution Policy exists to deal with bad faith registrations relatively inexpensively and quickly [3]. A complainant must assert three things together: that your .ca domain is confusingly similar to a Mark in which they had rights before your registration date and still hold, that you have no legitimate interest in the domain, and that you registered it in bad faith [3]. "Confusingly Similar" is assessed on whether the domain so nearly resembles the Mark in appearance, sound or ideas suggested that it is likely to be mistaken for it [3].
The defences are reassuring for an honest business. Legitimate interest is demonstrated by good-faith use of the domain as your own mark, by good-faith descriptive or generic use, by non-commercial use such as criticism or review, by the domain being your legal name or a name you are commonly known by, or by it being the geographical location of your place of business [3]. Bad faith, by contrast, covers registering primarily to resell to the rights holder above your costs, or a pattern of blocking registrations [3]. Ordinary businesses using their own name are not the target.
Do this this week
Three steps, about forty minutes. First, read the eighteen categories in CIRA's presence policy and identify, in writing, which one you fall under - and if it is the residency category, confirm the 183-day condition honestly [1]. Second, search your intended name in the Canadian trademarks database before you spend a dollar on signage, and check both the exact name and the obvious near-misses in your industry [5]. Third, register the .ca and the .com together if both are clear, point one at the other, and set a calendar reminder for renewal that is not tied to a single email address you might lose access to.
The domain ending is a ten-minute decision. The name is the one you live with.
