Hello Lynan,
What you're asking, then, is for Canadian sellers to sell your wares on your behalf. You say you have an ebay store, so I don't see the need to have others to hawk your wares for you. Moreover, I do not imagine most established sellers would want to act as a reseller for a product unless they are able to ascertain the reliability of that product. Add that to the considerable expense of shipping items through Canada Post. Why would that interest you? It is far cheaper to mail things from your own country.
If your product is any good at all, it will sell. And since you can offer exceptionally low shipping rates from where you are registered, - then if your customer service is first rate and you are always honest and trustworthy you will not need to piggy-back on Canadian sellers. You will be doing enviably well on your own.
It seems to me the thing to do is list your product on ebay like everyone else and sell internationally like other sellers. How successful you become will be up to you.
