- - Terms of service set the rules for using your website or service — what's allowed, what isn't, and the legal terms of the relationship between you and the user.
- Terms of service (sometimes called "terms of use") are the contract between your business and the people who use your website or platform.
New business owners setting up a website or launching an app often hear that they need "terms of service," "a privacy policy," and maybe "an EULA" — sometimes with no real explanation of what each one is for, or whether all three even apply. The result is a lot of copy-pasted boilerplate that doesn't actually do what the business thinks it does.
These three documents overlap in some ways but answer genuinely different questions. Understanding the difference matters because using the wrong one, or skipping one your business actually needs, leaves gaps.
The Short Answer: Three Different Jobs
- Terms of service set the rules for using your website or service — what's allowed, what isn't, and the legal terms of the relationship between you and the user.
- A privacy policy explains what personal information you collect and what you do with it.
- An EULA (end-user licence agreement) governs the use of software specifically — it grants a licence to use the software and sets limits on what the user can do with it, such as copying it or reverse-engineering it.

| Core legal basis | General contract law | Privacy law (PIPEDA, for Ontario businesses) | Contract law plus intellectual property licensing |
| Typical for | Any website, especially with accounts or transactions | Any site collecting personal data | Downloadable or installed software, apps |

Terms of Service, in Plain Language
Terms of service (sometimes called "terms of use") are the contract between your business and the people who use your website or platform. A good set of terms addresses acceptable use, account rules, payment terms if applicable, limitations on liability, and how disputes get resolved. Most businesses with any interactive website — accounts, purchases, uploads, bookings — benefit from having these in place, and they need to be presented in a way that actually creates a binding agreement, not just posted and forgotten.
Privacy Policy, in Plain Language
A privacy policy is specifically about personal information: what you collect, why, who you share it with, and how someone can ask questions or exercise their rights. It exists because Canadian privacy law generally requires businesses to be transparent about their data practices, not because it's a stylistic convention. It should reflect what your business actually does, not a generic template.
EULA, in Plain Language
An EULA is narrower and specific to software. If your business licenses software to users — a downloadable app, a desktop program, an embedded software component in a device — an EULA sets out what the user is and isn't allowed to do with it: how many devices they can install it on, whether they can copy or modify it, and who owns the underlying code. A website that doesn't distribute installable software generally doesn't need one; a SaaS platform accessed only through a browser is usually governed by terms of service rather than an EULA, though the line can blur for hybrid products.
Does Your Business Need All Three?
Not necessarily. A simple informational website with a contact form typically needs terms of service and a privacy policy, but not an EULA. A business distributing downloadable software or an app typically needs all three: terms covering the overall platform, a privacy policy for data practices, and an EULA specifically licensing the software itself. The right combination depends on what your business actually does — not on a one-size-fits-all list.
Frequently asked questions
Can we combine our terms of service and privacy policy into one document?
It's possible, but generally not advisable. They serve different purposes and different audiences find different sections relevant — combining them tends to make both harder to read and can obscure the specific disclosures a privacy policy is supposed to make clearly.
Do we need a lawyer for all three documents, or just the EULA?
All three are contracts, or in the privacy policy's case, a disclosure with real legal significance, and generic templates for any of them carry the same risk: they may not reflect what your business actually does, which can create problems later. Having each reviewed, even briefly, is worth it.
What happens if we just skip having any of these documents?
Without terms of service, you have fewer contractual protections and less clarity about the rules users are agreeing to. Without a privacy policy, you may not be meeting Canadian privacy law's transparency expectations. Skipping either isn't illegal in itself, but it removes tools that protect your business.
Does an EULA need to be a separate document from our terms of service?
Not necessarily — for simpler products, licence terms are sometimes folded into a single terms-of-service document. For more complex software, keeping a distinct EULA focused specifically on licensing terms tends to be clearer for both the business and the user.
