Oversight authorities allow the following types of consent EXCEPT?

Oversight authorities generally allow various forms of consent including implied consent, verbal consent, and written consent specific to the purpose for which the information is collected. However, they do not typically accept a "general consent" that covers all activities associated with the personal information. Consent must be specific and informed, clearly relating to the particular context in which personal information is to be used or disclosed. General consent fails to meet the specificity required under privacy laws like PIPEDA, which necessitates that consent be explicit for particularly sensitive information or whenever there is a significant change in the use of the information.
