Gasoline-powered vehicles could be off Quebec’s roads within 15 years, as the provincial government is anticipated to an ambitious new environmental plan this week. The anticipated announcement was welcomed by environmentalists on Saturday. “It’s a big step forward,” said Equiterre mobility analyst Andreanne Brazeau. “It sends a strong signal to the auto market and to consumers as well.” According to a La Presse report, Environment Minister Benoit Charette will announce a ban on the sale of new gas vehicles by 2035. The province currently offers a rebate of up to $8,000 on sales of electric cars, but George Iny of the Automobile Protection Association said consumers will need more than subsidies to make the switch.
