Based in Calgary and operated by Ultimarii Ltd., it serves energy companies, utilities, mining businesses, law firms, governments and regulators. Its platform lets professionals search regulatory records, ask questions about documents, review submissions and draft applications, responses and regulatory roadmaps.

These tools support infrastructure permitting, hearing preparation and other document-intensive regulatory work.
