Nowhere have I seen any evidence that Stop100 has enganged in discussions with the government, short of letters and emails to local MPPs. Perhaps, living in Ontario, you know more than I do.
FTFY. Ontario uses Members of Provincial Parliament instead of MLA's in provincial government.
Everyone has been bashing Ontario, but don't forget that after the fuel crisis of the 70's, Quebec, Newfoundland, and PEI also kept the lower limits of 100 km/h from the old 70 mph (113 km/h) limit beforehand (before Canada went metric). They're just as guilty

I have no relation, nor am I part of or affiliated to, Stop100.ca. I don't agree with their policy of raising the 401 to 130 km/h. I don't think any Canadian road could handle that speed, not with the climate here. But I think they have managed to raise some legitimate concerns regarding the issue.
I'm no road engineer (not yet anyway

), so I can't tell what standards Ontario uses to place speed limits on their roads. Quebec recently installed variable speed limit signs on their roads, which change according to conditions. I think that would be a smart move in Ontario for the MTO to consider.
Quite the debate here though, nice to see.
