The Globe and Mail reports in its Monday edition that Ottawa's new regulations that will tackle road pollution by Canadian drivers is back, and it is about as controversial as the previous regulations. The Globe's Adam Radwanski writes that since Prime Minister Mark Carney announced in early February that his government would jettison his predecessor Justin Trudeau's requirement that electric vehicles make up a growing share of all car sales, federal officials have placed a renewed emphasis on tailpipe standards, which set industry-wide requirements for reducing greenhouse gas emissions per vehicle and involve more flexible compliance approaches than just transitioning to EVs. But industry representatives are now saying Ottawa's new plans are also too difficult to meet. Carmakers are highly unlikely to make major changes to their products just for the Canadian market, so their response would probably involve adjusting which cars they try to sell most here, versus stateside. That prospect could, despite industry warnings about reducing consumers' choice, also have its upsides. For instance, Toyota's and Honda's Canadian assembly plants already make some of the more fuel-efficient gas-powered vehicles on the market.
