I can't help with with searching in Ontario but well the Gazing Globe balls are what we searching for, pay attention that they are not from glass and have not holes inside.. the best are 6 inch max 12 inch but the last one is very huge so 6 inch are the best.. I just ordered for myself 4 and 6 inch from better qaulity and nice price, the max price for 6 inch is between $14,00  to max $19,00 so watch out the prices they are huge in some stores even to $ 220 for small Gazing ball..
I have a link to a store with a cheap price and a very good quality "mirror balls" but have not the link under my hand i will post a little later today so check out..they shipping also worldwide...
I ordered many styles of the mirror balls in the past but was not so happy with the qaulity at all, in between you can play with a christmas silver ball ... :)
