The topic of Canadian's accepting British Peerages is an interesting and complex one. It is consistent today that we cannot accept them and retain our citizenship. However it was not always so. In fact in the early part of the 20th century it went back and forth quite a bit with Liberal governments apposing them but Conservative ones allowing them or relaxing rules. In 1964 the very powerful Ken Thomson (the commissioner of what is now considered the Thomson family tartan and powerful global media mogul) was appointed Baron Thomson of Fleet. He was such a powerful figure here it was wondered if the Liberal Prime Minister of the day Lester Pearson would have the nerve to stick to his position. It was answered the next day when the newspapers pressed Pearson for a comment. His reply was "I want to pass on my sincere congratulations to a former Canadian". Thomson went on to accept British citizenship which suited him quite well he said it allowed him to enjoy the best of both worlds. "in London I am addressed as Lord Thomson in Toronto everyone calls me Ken".
