Currently there is an exception for the five-year limit for dependants of Canadian Forces members residing abroad with those members, so no, they currently don't fall within the five-year rule.
If I may add to that, however, Bill C-76 will bring an improvement for the dependants of Canadian Forces members residing with them abroad and also to other civilians who accompany the Canadian Forces members abroad. For example, RCMP officers could be participating in a mission with the Canadian Forces, or Global Affairs Canada, GAC, officials could be participating in a mission as well. They would still vote under division 3 of part 11 of the act. Currently, they are experiencing some difficulties voting under that division, due to the fact that Canadian Forces members serve in remote areas. With the postal services in those areas, it might not always be easy to get their special ballot kit and send it back to Elections Canada so that it would be received before 6 p.m. on election day.
Bill C-76 brings with it a legal obligation for Elections Canada and the Canadian Armed Forces to collaborate in order to make sure these civilians who accompany the forces abroad, including dependants, have an easier way to vote.
