National Instrument 51-102 is a Canadian securities rule that requires public companies to regularly publish clear, standardized information about their finances and significant developments, such as quarterly and annual reports, management discussion and analysis, and notices of material changes. For investors it acts like a rule forcing businesses to keep their financial “windows” clear and up to date, making it easier to compare companies, spot risks, and make informed decisions.
