ChatGPT, Copilot or Claude: which one for a Quebec SME?

If your business already works in Outlook, Teams and SharePoint, Copilot is the simplest tool to roll out: it is switched on with a licence and reads what each employee is already allowed to see. If your teams mostly want to write, analyse and code, ChatGPT Business and Claude Team are close to equal, at the same entry price. None of the three guarantees today that your requests are processed in Canada.

That last point decides it for many Quebec SMEs. For everyday email, a cloud assistant is fine. For patient files, employee records or client documents under professional secrecy, you need either a solid assessment under Law 25 or sovereign AI that sends no data out.

All three vendors publish their rates. Here they are as shown on their official pages, before tax. Prices change often: check them when you buy.

Copilot plays at home in Microsoft 365. It summarises a Teams thread, drafts an Outlook reply from the attachments, finds a document in SharePoint. Its strength is integration: there is nothing to connect. Its limit is the same: outside the Microsoft ecosystem, it sees little.

ChatGPT Business is the most widespread general-purpose assistant. According to OpenAI’s pricing page, it connects to Google Workspace, Slack, GitHub and Microsoft 365, includes the Codex coding tool and lets you build workspace agents for custom workflows. It is often the best pick for a team that juggles several tools.

Claude is known for long-form writing, analysis of large documents and coding. The Team plan mirrors ChatGPT Business: a standard seat and a premium seat with five times the usage. The Enterprise plan separates the seat price from usage, which suits organisations that want to pay for actual consumption.

In all three cases, the tool remains an assistant: an employee asks, the AI answers. None of them will read your ERP on its own to enter an invoice or follow up with a client unless it is integrated. That difference between an assistant and an AI agent matters more than the choice of vendor.

Training. All three vendors commit not to train their models on data from their business plans by default. OpenAI says so for Business and Enterprise, Anthropic for Team and Enterprise, and Microsoft for prompts, responses and the data Copilot reads. Note that Anthropic’s individual plans (Free, Pro, Max) work the other way: the user must opt out. An employee using a personal account for work falls outside the business plan’s protection.

Storage. For a Canadian tenant, Microsoft stores Copilot interaction content at rest in Canada. OpenAI offers storage in Canada to new ChatGPT Enterprise and Edu customers, among ten regions. Anthropic offers no Canadian option in the Claude app. Canada is reachable only through the API, via Amazon Bedrock or Google Vertex.

Processing. This is where it counts, because the request and the documents read have to be decrypted to be processed. OpenAI guarantees in-region processing only in Europe, the United States and the UAE. Microsoft has announced in-country processing for Copilot. According to the April 3, 2026 update to its blog, Canada will follow in 2027. Until then, a request from a Quebec employee may be processed in the United States or elsewhere. Our article on Copilot and Law 25 covers this in detail.

Jurisdiction. OpenAI, Anthropic and Microsoft are US companies. The CLOUD Act lets US authorities compel data they control, wherever it is stored. A server in Montreal does not change that. Our article on the CLOUD Act explains why.

Law 25 bans none of these tools. Section 17 of Quebec’s private sector privacy act does, however, require a privacy impact assessment before personal information is communicated outside Quebec, taking into account its sensitivity, the purpose, the protection measures and the legal framework of the place where it will be communicated.

In practice, three decisions come before rolling out an assistant: what data employees may enter, which plan is authorised (never personal accounts) and who keeps the assessment current. A one-page AI acceptable use policy covers most of it.

Sovereign AI runs an open-weight model on a server the business owns, or with a Canadian-owned host in Quebec. Requests, documents and answers never leave that infrastructure. The question of where processing happens disappears, and so does the CLOUD Act question.

To be fair: self-hosted models do not always match the best cloud models on the most complex reasoning, and they need a server, an installation and upkeep. On the other hand, for reading invoices, sorting email, summarising files or answering from your own documents, recent open models are more than enough. Our model rankings compare them.

Many businesses combine the two: a cloud assistant for everyday work without sensitive data, and sovereign agents connected to the ERP for anything involving clients, employees or patients. That is Cogio’s approach: agents hosted at the client’s, working inside its systems with human approval at the steps that commit the business.

The last question is often the most important. An assistant saves each person a few minutes. A well-integrated agent removes a whole task. Our article Power Automate, Zapier or an AI agent covers that distinction.
