SaskPower, the province's electrical utility, plans grid upgrades for any large new power user as part of its routine infrastructure work, which can mean construction disruption nearby but is a separate question from property value. Zoning and land use around a major new development are set by the City of Saskatoon, and any resulting change to a nearby assessment can be appealed to the Board of Revision.
Saskatoon's benchmark price moved 2.8 percent year over year in the latest Saskatchewan REALTORS Association report, and a single development, on its own, is unlikely to move a citywide figure like that by much. Any real effect would show up first on the specific streets closest to the site, not in that broader number.
