your fees with a Mileage plus award would be $90.06cnd. ( aeroplan rip off $214) there is a flight from ORD-OGG nonstop 777 on weekends however its doubtful Aeroplan would have award space in Business class. ( however there is probably economy as its showing on mileage plus) Air Canada does starnet blocking so keep your fingers crossed.

Consider flying to HNL and buying a ticket inter island.
there is lots of space yyz-lax and SFO on AC in business class so book quickly before that space disappears.
reality is you are stuck with aeroplan miles use them up and start putting credit card miles to something more useful. live and learn.
