Thanks Everyone, we took a look at the Allears site and read their info on upgrading tickets - seems we can upgrade from a child hopper to adult hopper by paying the difference - we had a $500 USD Visa Debit Card from DVC that was burining a hole in our pocket so we went to DS last night and bought 2 kids 7 day hopper passes for $258.80 CDN each (taxes included - works out to $208.65 USD) and will go to Guest Services on arrival at WDW to upgrade - best part is with the exchange we still have $78 USD left on the debit card to put toward our upgrade
I called all the stores in the Toronto area and most only had kids passes or adult passes that were the hoppers plus water parks etc. - more than we needed.
One CM did tell me that they don't expect any new shipments of passes until January and likely a price increase/rightsizing due to the fact that current passes are at par and the CDN dollar has dropped.
I compared the CAA prices for adult 7 day hoppers and those are $290.15 USD taxes in so almost $358.28 CDN - the adult DS 7 day passes are $296.07 CDN so would be $238.43 USD if you could get them - savings of $62.21 CDN (hope my math is right on this - i was getting a bit confused with all the exchange and MYW options). I believe Scarborough Town Centre DS has adult and children 7 day MYW plus hopper, plus waterpark passes in stock if you are looking for those - $349.34/$312.07 CDN each includes taxes. At the Gate at WDW these would cost approx. $433/387 CDN.
Hope this info can help someone else.
