Question about buying Carter BBD for my 318 (unless I should look at something else)

I'm going to try this:

Based on some web searching I've just done, I'm reading conflicting info about which gasoline brands and which octane has or doesn't have ethanol here in Ontario.

I was assuming any gas I buy anywhere, regardless of octane, has 10% enthanol. Maybe not?
Depends on which Province or State you’re in. Here in BC, Chevron has 94 octane which contains NO ethanol and it also has its own hose so you’re not getting drips of ethanol from a previous user who filled with 87, 89 or 91. I‘m not sure if Chevron is in Ontario but Shell is for sure.

Shell offers 93 Nitro but it’s not clear if it contains ethanol or not. If there isn’t a sticker stating ‘no ethanol’ then it likely has a small % of ethanol in it. And if uses the same hose as the lower grades, then for sure it has ethanol in it.
