Not sure about across the border, but up here different companies have different amounts of ethanol as per Ontario regulations. But I could be wrong! Although I did notice better power and far less black soot on my bumper when I switched from petrol 15% ethanol 94 octane to 0% ethanol 91 octane shell.
