I've looked and I haven't found any. Resorted to using ethanol-free (i.e. 94-grade) from Chevron when I used to trailer - cheated and used regular if I knew I was going to be using it quickly.
Good luck, let us know if you find a place that carries it.
FWIW, if you are using the fuel dock, I've found Mosquito Creek to be cheaper if prices are going up, and better prices at the Chevron barge in Coal Harbour when prices are dropping. Mosquito Creek only gets refilled every few weeks and I think they price the fuel off that last delivery.
