Canadian citizenship is not easy to re-acquire once you have lost it.    I have been trying for 13 years.   If there had been a judicial process in place for revocation back then,   thousands of quite law-abiding Canadians would have at least been able to try to prevent that happening.   It was a shock for so many of us to apply for a document like a passport renewal or a service to be told our citizenship was stripped when we had done nothing wrong,  just fell into one of the categories deemed un-Canadian (i.e. being born out of wedlock in WWII is just one example,  or failing to re-affirm citizenship by your 28th birthday, of which no one knew, or ten other crazy reasons.)  I think that ease of stripping citizenship really devalued Canadian citizenship, if anything did.
