Partly, and most answers to this question only cover half of it. Storing your data in Canada is easy. Running the model on that data inside Canada is the hard half, because the strongest commercial models are hosted in the United States. Ask about both separately.
If you only ask one question, ask the second one.
Data residency is where your documents sit when nobody is using them. Your files, your database, your backups. This is a solved problem. Azure, AWS and Google all run Canadian regions, and so does Supabase and most of the storage layer you would use.
Inference residency is where the computer runs when the model actually reads your document. This is the part that is not solved, and it is the part procurement teams miss until late in a review.
These are the three deployment paths we worked through for a Canadian quantity surveying firm whose federal work made US data handling a hard gate.
| Option | Where inference runs | What you give up |
|---|---|---|
| Direct to a US-hosted model | United States | Nothing on capability. You get the strongest models. You are relying on contract terms rather than geography, so this fails a hard residency gate. |
| A Canadian cloud region | Canada | Model choice and release timing. Canada-only processing currently means specific OpenAI models in Azure's Canada East region; Claude can keep data stored in Canada, but its processing runs outside Canada. New versions arrive later and it costs more per token. |
| Open-weight model, your infrastructure | Wherever you put it, including on-premise | Capability and effort. Open-weight models trail the frontier, and you now own the hosting, the updates and the security of a GPU environment. |
For the engagement above, the residency position was set out as a short document before any work started, rather than as a clause buried in a contract. It committed to 100 percent of client data at rest in Canada, zero protected documents retained by ResonAi, and nine written commitments, with two decisions left explicitly open for the client to make.
Leaving two decisions open was the useful part. A residency document that answers everything on the first pass is usually hiding the questions the consultant has not thought about yet.
There are a lot of small Canadian firms doing this work, and most can meet a storage residency requirement without difficulty. Fewer have worked through the inference question with a client who had a hard gate. If a consultant answers "yes, everything stays in Canada" without asking which of the two questions you mean, they have not done it before.
