It starts with 3 cents a litre in 2015 and will only go up from there.
A gas tax is one of the recommendations from a panel focusing on how the province can pay for transit expansion in the GTHA - namely the $50 billion Big Move plan proposed by Metrolinx.
There are two gas tax options. One, maxes out at 5 cents a litre and the other 10 cents a litre.
Panel head Anne Golden says while everyone in the province would have to pay they won't be funding public transit in the GTHA. Money raised in Timmins or North Bay would go to other infrastructure projects around the province.
Other recommendations: a corporate tax hike and moving around some of the revenue made off the the HST.
The Golden panel doesn't recommend road tolls or parking levies, calling them too complicated to implement.
It also recommends setting up a trust for all dedicated transit funding.
The strategy outlined in the panel's report would bring in between $1.7-$1.8 billion each year for the province when fully implemented.
The province would still have to adopt these recommendations.
