Maybe maybe not but it's still up to whoever inspects the package at the Point of Entry. The CBSA plays by their own rules and although you have a chance of appealing the seizure, do you really want to go through all the headache?
I personally wouldn't try it because I have better things to do with my personal time but if you've got nothing better to do than go back and forth between yourself and the CBSA/RCMP and get it sent to a lab for testing and all that then by all means go ahead but realize in the worst case you'd waste a lot of time.
