Query **956 Canadian federal Acts** -- from PIPEDA and the Criminal Code to the Competition Act, Bank Act, Copyright Act, and more -- directly from Claude, Cursor, or any MCP-compatible client.

If you're building legal tech, compliance tools, or doing Canadian legal research, this is your verified reference database.

Built by [Ansvar Systems](https://ansvar.eu) -- Stockholm, Sweden

## Why This Exists

Canadian federal law research means navigating [laws-lois.justice.gc.ca](https://laws-lois.justice.gc.ca), downloading HTML pages across a bilingual site, and manually cross-referencing between Acts and sections. Whether you're:

- A **lawyer** validating citations in a brief or contract
- A **compliance officer** checking PIPEDA obligations or CASL requirements
- A **legal tech developer** building tools on Canadian law
- A **researcher** tracing legislative provisions across 956 federal Acts

...you shouldn't need dozens of browser tabs and manual cross-referencing. Ask Claude. Get the exact provision. With context.

This MCP server makes Canadian law **searchable, cross-referenceable, and AI-readable**.
