PIPEDA (Personal Information Protection and Electronic Documents Act) regulates how private-sector organizations collect, use, and disclose personal information in the course of commercial business. The act specifies that personal information includes details such as age, name, ID numbers, income, ethnic origin, opinions, evaluations, comments, etc.
Among the options provided, the ethnic composition within a neighborhood is not typically considered personal information under PIPEDA. The act primarily focuses on protecting individuals' personal and sensitive information, such as medical diagnosis, tax returns, residential address, credit history, and financial transactions, which are all critical aspects regulated by PIPEDA to ensure privacy and confidentiality.
