Defense Community Banking has existed in some for a long time(two decades I think), essentially every national bank wants a shot at ~100K government employee's pay...
The CAF has a small impact in places like Ottawa, Kingston, Halifax, etc., but in towns like Oromocto, the posting cycle is a significant factor in housing prices.
The CAF shat the bed when it decided to abandon RHUs, and barracks/apartments. It was a penny-wise, but pound-foolish decision made when it was "impossible" to lose money buying a house 20 years ago. The people who made the decisions are long since retired, so the people in charge today are now left holding the bag.
If the CAF had been even remotely smart back in the last recession, it would have invested in modern "living in" barracks, and apartments at all of its bases, as well as pushed CFHA to build more RHUs. The writing has been on the wall for a long time, but too many of the bosses have been ignoring the problem while "cashing in" on each subsequent posting. If have to listen to another MWO/CWO brag about how much they made on their latest posting I might end up on CTV news...
