In Canada most gas stations (maybe all) have alcohol free gas if you buy their highest octane premium gas, all lower grades have 10% alcohol. However, that hose from somewhere inside the pump to the nozzle end is full of whatever gas the previous customer selected and you are going to get all of it and it's probably low grade, as that is the most popular. If you are filling a small container ( 1 gal./4 L) you could end up with a significant percent of alcohol, not so bad if you are filling a larger container. Best approach is to pump the first .5 gal/2 L into your vehicle's tank before filling your container.
