What principle in PIPEDA stipulates that knowledge and consent of the individual are required for the collection of personal information?

The principle in PIPEDA that mandates the knowledge and consent of the individual for the collection of personal information is rooted in the principle of consent. This principle emphasizes that individuals should be fully aware when their personal information is being collected and must provide their explicit permission for this process. Consent must be informed, meaning that individuals should understand what they are consenting to, including the purpose of the data collection and how their information will be used or disclosed.

The requirement for consent is fundamental in privacy legislation, ensuring that individuals retain control over their personal information and fostering trust between individuals and organizations that handle such data. The principle also recognizes that consent can be withdrawn, aligning with the notion of individual autonomy and control over personal data.

In contrast, other principles like accountability focus on an organization’s responsibility for managing personal information, disclosure pertains to how information is shared, and retention relates to how long data is kept. While these are all important aspects of data privacy, they do not specifically address the necessity for the individual's consent prior to data collection.
