Drug Offences (CDSA)Hybrid
CDSA-4

Possession of Substance

Possession of substance

Drug Offences
Maximum Sentence

7 years (Schedule I) / 3 years (Schedule III)

Classification: Hybrid
🍁 Immigration Impact

Hybrid offence under CDSA. Schedule I possession with a 7-year maximum creates inadmissibility under IRPA s.36(2). Cannabis possession has been legal in Canada since October 2018 (Cannabis Act): foreign cannabis possession convictions may no longer have a Canadian equivalent. Other drug possession remains grounds for inadmissibility.

🍁 In Simple Terms

Having a controlled drug on you without authorization. Schedule I substances carry up to 7 years and Schedule III up to 3, both below the serious criminality line but still enough to make a foreign national inadmissible. Cannabis is the exception, because possession has been legal in Canada since October 2018 and an old foreign conviction may no longer match any Canadian offence.
