Final answer:
The Personal Information Protection and Electronic Documents Act (PIPEDA) regulates privacy standards in most Canadian provinces, balancing individual privacy rights with the needs of businesses.
Step-by-step explanation:
The law that regulates privacy standards in most Canadian provinces is the Personal Information Protection and Electronic Documents Act (PIPEDA). PIPEDA sets the ground rules for how private sector organizations collect, use, and disclose personal information in the course of commercial activities across Canada. It is designed to balance individual privacy rights with the needs of businesses to collect and use personal information. The act applies to personal information held by businesses in all provinces that do not have their own privacy laws. In provinces with their own laws, PIPEDA still covers federally regulated organizations.
