I am fortunate to boat in an area where the US is a stone throw away from us. Over the last 20 years I have fuelled up 90% of the time on the US side simply because it was so much cheaper however not so any more.

With high exchange rates, diesel prices at the marinas in my location are cheaper in Canada this year. My marina is at 1.39/l CDN which equates to $5.26 cdn/US Gal. On the NY side at the cheapest place I know, diesel is at $4.52US which equates to $5.95 CDN. Never before have I seen the rates cheaper in Canada. Guess I will be filling in Canada this year for a change.
