That would be an issue of trust, but through the regulations, as we currently have them, you can't just start shooting at IPSC. You have to take the black badge course and maintain a certain amount of participation to maintain it. If you do not participate for two years, you lose your black badge qualification and have to either retake it....
As far as an influx is concerned. if we are the only handgun sport in Canada, we would presume that people who want to go to the Olympics and preliminarily do other sports will join. That statement came based on the fact that at this point our instructors are flat out. We'd need a larger group to start doing it, and we would probably need accommodation. The ranges would not be able to handle such a great influx.
