In my experience, having coordinated all the implementation preparations for the 2009 legislative amendments to restore citizenship to lost Canadians, as well as the changes in 2015, I can say with confidence that the preparations generally take a year. You normally have IT changes to facilitate the processing of the new types of cases that the department needs to facilitate. It's using existing processes, as the member mentioned, but still IT changes are required. There are generally always some regulatory changes required. The regulatory process takes a minimum of a year, and the IT changes generally as well.
Many other changes are done in parallel to support those two processes in terms of any changes to policy guidelines, training for officers, communications with members of the public who are benefiting and so on and so forth.
Thank you.
