Choosing software with Canadian data residency under Law 25 and PIPEDA

Data residency is about where information physically lives. A vendor with Canadian data residency stores and processes your records in Canadian data centres rather than routing them through infrastructure abroad.

Neither federal nor Quebec law imposes a blanket localization rule on private-sector organizations. PIPEDA allows personal information to be transferred to a third party for processing, but the organization that collected it remains accountable for that information and is expected to use contractual or other means to provide a comparable level of protection. Quebec's Law 25 goes further: before communicating personal information outside Quebec, an organization must assess whether the information will receive adequate protection, taking the legal framework of the destination into account.

The practical result is that residency is rarely mandatory on its own, but keeping data in Canada removes an entire assessment and disclosure burden. For many clients, public bodies, and law firms it has simply become a procurement requirement.

Questions worth asking any vendor:

• Where are the primary and backup data centres located?

• Is data ever processed, cached, or supported from outside Canada?

• Which subprocessors touch the data, and where are they?

• Is data encrypted at rest and in transit, and who holds the keys?

• What happens to the data when the contract ends?

The answers matter more than the marketing claim. "Canadian company" and "Canadian hosting" are not the same thing, and support access from another jurisdiction is the detail most often missed.
