There were a few knighthoods as well as a few peerages. There were others that were done rather quietly because they held dual British/Canadian citizenship, it only became an issue with Prime Minister Chrétien in the Black case. Nickle was/is/has been cited or ignored when convenient. That being said with the present Canadian and Provincial Honours programs in place I doubt there will any others.

It will be interesting to see how this case before the Lords plays out as it could have far reaching implications if the DNA evidence is accepted. It would open some challenges to some other peerages and there may be some others resurrected. Many may be scared! If I had to guess, I'd say they may ignore the DNA.
