Legal AI Buyer Guide
How to evaluate AI for a Canadian law firm
A practical framework for assessing legal AI through confidentiality, source review, data residency, workflow fit, and lawyer control.
The most persuasive AI demonstration is not always the best guide to how a product will behave inside a live legal matter. A useful evaluation starts with the work, people, and responsibilities the technology must support.
Begin with the matter, not the model
Ask vendors to show how the product handles a realistic file from beginning to end. A legal team needs more than a good answer in isolation. It needs to understand which documents were considered, where the answer came from, and how the work remains connected to the file.
A focused pilot should use a defined matter type and a small group of people who can compare the new workflow with the way the same work is handled today.
- Can a lawyer move from an answer back to the supporting record?
- Does useful context stay with the matter across sessions and handoffs?
- Can the team review, refine, and correct the work before relying on it?
Make confidentiality questions concrete
Security language is most useful when it answers practical questions. Firms should know where matter information is stored, who can access it, how organizations and matters stay separate, and whether customer content is used to train shared models.
The right answers should be understandable to firm leadership, legal professionals, clients, and procurement reviewers without requiring them to interpret infrastructure jargon.
- Where is customer data stored and processed?
- How are identity, role, organization, and matter access enforced?
- What activity is retained for later review?
- What happens to customer information when the relationship ends?
Measure adoption through useful work
A pilot should measure whether people can complete meaningful work with less searching, rebuilding, and administrative friction. Usage counts alone do not show whether a legal team is gaining confidence or capacity.
Useful measures include time to understand an inherited file, time spent locating supporting material, speed of a handoff, and the amount of non-billable coordination required to keep a client informed.
Keep professional judgment visible
Legal AI should make review easier, not make review feel optional. Define who remains responsible for approving work, how source material is checked, and which activities must stay outside automated workflows.
The strongest evaluation is one where lawyers can explain both the benefit and the boundary of the technology in plain language.
