Well, potential administrators will need to apply to the different jurisdictions they want to offer PRPPs in. At the federal level they would apply to OSFI, and at the provincial level they would go to the relevant administrator.
The legislation builds in the ability of the different jurisdictions to delegate the licensing process to each other, so if a province does not want to build the structures needed to essentially create the licensing scheme, they could by agreement delegate that to OSFI, for example.
