Importing and exporting: (CDSA, section 6)
(except as authorized) no person shall import into Canada or export from Canada a substance included in Schedule I-IV. You may also not possess it for the purposes of exporting.
Now, everyone who does this and the drug is either Schedule III or IV
i) is guilty of an indictable offence and liable to prison for a term not exceeding ten years, or
ii) is guilty of a summary conviction and liable to a term not exceeding 18 months
So basically, if you are caught getting anything imported into Canada, you can be charged pretty heavy. Or if you get caught even sending a few amps of cyp to the US, you can still be charged heavily. However, youd probably be charged on summary punishment if anything and again, thats not as serious
