The RDOS recently followed the lead of other regional districts in the Okanagan and awarded a grant to the Okanagan Film Commission. I am against such grants/subsidies for many reasons. But the most important is that the economic impact of film production in the Okanagan is negligible. Indeed, the economic impact of the entire tourism sector is much smaller than most people realize.
I collected some census data and submitted a report to the RDOS board in order to back up these claims. The full report can be found here, although the central argument is captured in the graphic below
Since submitting my report, BC Statistics has issued a much better, more comprehensive report that addresses the same question: What drives the economies of BC regions? A good summary of this report appeared in the Penticton Herald (link). This is recommended reading for everyone who thinks Penticton is the city of peaches and beaches.
