Terms of use

Last updated: September 1, 2026

These terms apply when you visit the DDA website or use its public diagnostic tools.

Acceptable use

You may browse the site, share links, quote brief passages with attribution, and use public tools for lawful informational purposes. You may not interfere with the site, bypass security controls, introduce malicious code, scrape the site in a way that disrupts service, or misrepresent DDA content as your own.

Diagnostic tools

Tool outputs depend on the information entered and the assumptions described by each tool. Outputs are informational and may not reflect current law, rates, market conditions, or the facts of a particular organization. Review the inputs and obtain the appropriate professional advice before acting on a result.

Intellectual property

DDA retains its rights in original website content, models, methods, interfaces, and tools. Permission to use the public site does not transfer ownership or grant a licence to reproduce, reverse engineer, resell, or create a competing product from protected material.

No client relationship

Use of the site or a diagnostic tool does not create a client relationship. Sending an inquiry does not require DDA to accept an engagement. Project work begins only under written terms agreed by the parties.

Availability and responsibility

The site may be changed, interrupted, or withdrawn. To the extent permitted by law, DDA is not responsible for losses arising from reliance on general website content, tool outputs, third-party links, or information entered incorrectly.

Governing law

These terms are governed by the laws of British Columbia and the applicable laws of Canada.
