Yes, you got an input credit.... GST is an in out entry. Unlike PST, even if you resell, you pay GST on the goods you buy and use in your enterprise, (input credit) and collect GST on goods sold within Canada.
Now if you sell outside of the country, you don't collect GST on the sale, but you still get the input credit on the GST you paid on the original inventory for resale.
So yes, you may end up getting a refund on the GST you paid if you did not collect enough GST to offset, due to non-tax sales, etc.
