To speak of urban centres, I think of Toronto, where a lot of people are posted in and out. The 4th division is there. The support group is there along with 32 brigade and a bunch of reserve and cadet units. There are people posted in from bases across the country at various ranks. If you're a private, corporal or lieutenant, it's going to be a pretty big hardship for you to get housing and afford the cost of living if you don't already have friends or can find a roommate or maybe have family in the city.
On base, there is an appetite for condo or apartment-style housing in favour of the traditional houses. Not everybody wants a house. Not everybody wants to maintain a property. Some people just want a quiet space. There is diversity among the demand, so it is definitely there.
