Vibe coded app testing in Montreal
What a Montreal founder pays to have an AI-built app security and QA tested, what Law 25 asks of it, and which Montreal buyers will want proof.
A Montreal company can have an AI-built app security and QA tested for $2,000 to $12,000 CAD, the same as anywhere in Canada, because testing is remote and billed in tester days. What differs in Montreal is the law and the buyers. Personal information collected by a Quebec business falls under Law 25, health information under Law 25, and the customers most likely to ask a Montreal startup how its product was tested work in artificial intelligence research and aerospace.

Who asks a Montreal founder for a test
Quebec companies answer to Law 25 rather than PIPEDA, which carries its own breach reporting duties, privacy impact assessment requirement and penalties of up to four percent of worldwide turnover. A compliance program built only against PIPEDA will not satisfy a Quebec customer.
The sectors shaping demand in Montreal are artificial intelligence research, aerospace, video games, logistics. Each asks a different question of an AI-built product. A buyer in artificial intelligence research usually sends a security questionnaire and wants a penetration test summary with the high findings closed. A buyer in aerospace tends to ask where data is stored and whether customer data reaches an AI model. A partner in video games often passes down whatever its own auditor asked for. Knowing which of these you are answering in Montreal sets the scope before you collect quotes.
What Law 25 means for an AI feature in Quebec
Law 25 applies to how a Quebec business collects, uses and discloses personal information, whoever wrote the code. For an app with AI features, three duties come up first: being transparent that data goes to a model provider, protecting it through that provider's terms, and being able to detect, record and report a breach. A database left open by a missing rule is a breach under Law 25 on the day someone reads it. The longer version is on privacy law for AI apps, and Law 25 matters to any Montreal app with users in Quebec.
If the app touches health information, Law 25 adds its own rules for agents and service providers in Quebec. Sending that information to a model provider needs an assessment under Law 25 before launch, not after a customer asks.
What a test covers
| Area | Why it matters to artificial intelligence research buyers |
|---|---|
| Access between users and customers | The first thing an artificial intelligence research security review checks |
| Supabase or Firebase rules | Where most AI-built apps leak data |
| Secrets in front-end code | Leaked keys are an incident under Law 25 if they reach personal information |
| Payments | Billing errors reach Montreal customers before anyone notices |
| AI features | Prompt injection and data leakage, mapped to the OWASP LLM Top 10 |
| QA of core flows | Bugs your first Montreal users would otherwise find |
The detail is on security testing, QA testing and the AI security assessment.

Testing is remote, so a Montreal company is not limited to firms in Quebec. Ask how many tester days each quote covers, and price your scope first with the cost estimator.

Do I need a tester based in Montreal?
No. Testing is remote. A local firm helps if an artificial intelligence research buyer wants an on-site meeting or if you prefer to deal in person.
Which privacy law covers my Montreal app?
Law 25 for personal information in Quebec, plus Law 25 for users in Quebec and Law 25 for health information. General information, not legal advice.
How long does a test take for a Montreal startup?
One to three weeks from scoping to report for a small app, the same as anywhere else in Canada.
