The protections that exist in the current Citizenship Act with respect to renunciation proceedings are very slim. The protections with regard to revocation proceedings are somewhat more robust.
I think the experience of the United Kingdom is instructive in that there has been almost no or the thinnest of due process protections under the 2006 revision to the legislation, and the courts have held...and this is in a jurisdiction that is quite similar to Canada's.
There have been enormous problems for the U.K. government in trying to effect these citizenship stripping proceedings, for lack of a better word, because it's not really renunciation or revocation. A recent estimate is that it has cost about $3.5 million for each level of appeal. So in making those attempts to remove a number of people from the processes of justice of a western country, the U.K. has spent in excess of $40 million, and the costs continue to rise.
