I have seen no requirement that sulphur be removed from gasoline in
the US, what requirements are up north in Canada I can not speak to.
But unless you remove all the sulphur you still will get sulphuric
acid.

Like the Tier 2 program, the Tier 3 program considers the vehicle and
its fuel as an integrated system to reduce the impacts of motor vehicles
on air quality and public health. The program sets new vehicle emissions
standards and lowers the sulfur content of gasoline to a maximum of
10ppm beginning in 2017. The vehicle standards will reduce both tailpipe
and evaporative emissions from passenger cars, light-duty trucks,
medium-duty passenger vehicles, and some heavy-duty vehicles. The
gasoline sulfur standard will enable more stringent vehicle emissions
standards and will make emissions control systems more effective. It
will also reduce the emissions of the existing fleet of vehicles.
