A Canadian securities regulation that sets the rules for using a short-form prospectus when a company offers securities to the public across provinces, specifying what information must be disclosed and how the offering is conducted. It matters to investors because it creates a standardized, checklist-style presentation of key facts about the issuer and the deal—like a clear, required information sheet—so buyers can compare offerings and know there are regulatory safeguards and timelines in place.

Think of it as an independent inspector’s blueprint that explains the data, methods, and uncertainties behind those estimates so investors can judge how reliable the claims are and compare projects on a consistent basis.
