Citation validation for Canadian law.

Maple Juris verifies legal citations against a structured graph of federal and Ontario legislation - returning the real provision, its exact text, and a validity score. Data validation for citations, context, and case law - deterministic verification built for all areas of law.

What we offer

What every input gets you.

Citation validation

Give us a statute, section, and jurisdiction. We confirm whether it resolves to a real, in-force provision and return the exact statutory text.

Graph-backed retrieval

A structured knowledge graph encodes the hierarchy, amendment history, and temporal versions of Canadian legislation - not a flat text search.

Validity scoring

Every result carries a validity score. A less than full score points you to missing context - usually a jurisdiction or a fuller citation. We never predictively generate an answer for you like an LLM does.

Corpus

Coverage by jurisdiction.

Custom

Let’s talk

For platforms, firms and public bodies whose requirements the standard plans cannot express.

Credit volume and pricing set to your workload
The only plan that can grant Artificial Intelligence, Machine Learning, Fine-Tuning and Model Training rights
Platform and embedding rights - one account standing behind your own customers
Attribution removal and white-labelling
Contract, indemnity and service-level terms negotiated with you
Data processing agreement, security review and procurement support
Additional jurisdictions and sources scoped into your agreement
Forward deployed engineering scoped into your agreement, rather than bought by the hour

All prices are in Canadian dollars. The Free and Research plans are for personal and academic use only: commercial production use and training purposes are not allowed.

We aim to respond the same business day, but response times and uptime are targets, not guarantees. No plan carries a service level agreement.

Visible attribution is required wherever results are delivered to an organization or to anyone other than you - in a product, in a marketing or demonstration capacity, or under a contractual agreement. See Attribution in the Terms and the form specified in the API docs; the right to remove it is available only by negotiation.
