For example, a lot of the requests Citizenship and Immigration receives for information that would traditionally be considered personal information requests are handled through the Access to Information Act. Because of some of the wording of the legislation, because the individual is located outside Canada and is not a Canadian citizen, they still have a means to obtaining the information they would need for processing their immigration file. They go through a person present in Canada to represent them and obtain that information. It's unclear how many additional requests opening the Privacy Act to a broader audience would change.
