A growing body of evidence shows that sales mandates are effective at significantly increasing ZEV sales.
A 2025 study that simulated the impact of a ZEV sales mandate and other policies in Canada found that a, “strong ZEV sales standard can induce 95−100% ZEV sales by 2035, while inducing more ZEV-supportive strategies by the automakers, including an average 22% reduction in the prices of ZEVs, a 6% increase in the price of conventional vehicles, and a doubling of ZEV-related Research & Development (R&D) investment.”1
We can see this in the real world too, by comparing ZEV sales in provinces and territories both with and without provincial sales mandates. In 2024, ZEVs represented 13.8% of new cars sold in Canada. The number was much higher in provinces with sales mandates and provincial rebates: 30.1% in Quebec and 20.7% in B.C.2
