I'm not sure about future development in some of the unincorporated communities in the Capital Region like Lorette, Oakbank and La Salle but Qualico has two significant developments coming up soon, Taylor Farm in Headingley and the expansion of Oak Bluff West. These two alone will probably close to double Oak Bluff's population in the next 5 years or so and Taylor Farm should easily add another 1,000 residents to Headingley in the near future.
Also, the Quarry Ridge Park development in Stonewall should grow that community to closer to 10,000 in about 20 years.
