When I left Valcartier 4 years ago, they were in the process of building a very decent built-up area, consisting of permanent, multi-floor buildings. It already had 2 or 3 large buildings built around a T-junction and a "fire house". I believe they had plans to build more. It is in the old "Camp Dubé" area.
I am posted back there this summer, so I will investigate this further and post pics.
