What shipping service?
If it was airmail then it turns into Canada Post. In this case, it may be inspected and they will charge you $8 for that and any GST if it's over a certain amount, and depending on what type of item it is. (only if it's inspected though, which sometimes doesn't happen)
If it was UPS, expect to get raped with brokerage fees.
