It can take up to 24 hours for a listing to "index" and appear on eBay. If you are listing items that are high-value or high fraud categories, or that are monitored by the VERO program, it takes longer than if you were listing, for example vintage paperbacks.
If you were listing on eBaydotCOM and did not make your items available to dotCA, you will not see the items on dotCA. And vice versa
Did the eBay consultant mention that should one of your items sell, the payment will not be released to you for up to 21 days, but that you have to ship within 7 days to keep your Seller Protection?
