Why does US gas go further than Canadian gas? (fuel, octane, miles per gallon)

I've noticed for years now, that if I fill up across the border in Buffalo, the gas seems to last a really long time. During the summer we tested it a couple of times. A full tank of US gas took us all the way to the cottage and back home. A full tank of Canadian gas did not. We had to stop and fill up about 90 mins before getting home.
So I estimate we get 20 miles per gallon on US fuel and only 15 miles per gallon on Canadian. A secondary benefit is that it cost only $60 to fill it in the US, and $85 in Canada.
Well I'm just using a full tank to compare. We buy gas in litres in Canada and drive in km. I'm just assuming my tank holds 15 gallons. I think the octanes/ethanol percentages are the same... and my cottage round-trip is 300 miles.
What's E10, mike? 10% ethanol? I think they both are. I don't know. The only variable in my comparison is the difference between regular gas in the US and regular gas in Canada and I've no idea what those are. I thought someone here might know.

Yes, 10% Ethanol blend fuel (90% gasoline/10% ethanol) is pretty common in my area. But other areas have gas that is 100% pure gasoline. It should say on the pump is the fuel contains 10% ethanol.
Ethanol gas isn't as potent as pure 100% gasoline, so there is a reduction in fuel economy.
I'm pretty sure you can get E10 gas in Canada. But that would be one thing to check into is the ethanol content of the different gas you are buying.
Same gas but I think it is because gravity is 13 meters/(sec*sec) in Canada and only 9.8 here so there is more drag and friction and the MPG is proportionately less.
Yes just checked, it's E10 here as well but if it wasn't, then wouldn't it be all the more mysterious that the E10 gets us further?

Gravity? But it's the same drive each time, and the same driver, even. Chester, are you really suggesting that southern Ontario in general gets poorer gas mileage than Western NY because of a difference in gravity?
