I can answer that one for CFB Borden. CFB Borden has destroyed a tremendous number of old PMQs within the last 10 to 15 years. That is causing a housing problem for the soldiers. The infrastructure like the water and the sanitary systems are still in place, but the houses are not there anymore. It would take nothing to put trailers or mini-homes there.
