That process is the same one Saskatoon uses for any large industrial user: a rezoning or development permit application, public notice, and City of Saskatoon council approval where required. A data centre proposal would be evaluated on its own merits within that existing framework, not under emergency or temporary rules.
For a Saskatoon homeowner, the more relevant question is how a large new industrial user affects the immediate neighbourhood, not the city as a whole. Saskatoon's benchmark price of $444,700 reflects every neighbourhood in the city combined, so a localized effect near one development would show up in nearby comparable sales long before it moved that citywide figure.
