I hope this welcome ruling will not be appealed by the government .

The vast majority who  lost citizenship  were just ordinary Canadians who lived, worked, and contributed to Canada.  My family learned ours was stripped in late 2003, after 58 years in Canada with no notice, hearing or way to appeal.  Some groups lost for being a War Bride , child of a War Bride,  out of the country more than 5 years prior to 1947 (my father, with the Royal Canadian Artillery in WWII),  born prior to marriage(common in WWII due to military orders) failing to reaffirm citizenship before  28th birthday(who knew?) etc.

It may be too late for my brother and I to  get our citizenship back(nothing worked so far) Our  children, all good citizens of Canada, are entitled to British citizenship due to having a parent born in WWII Britain and grandparents serving in Canadian  forces. Due to Bill C-24 they are Second Class,, vulnerable to revocation. At least they will get a judicial process before it is taken.
