5 years less a day (indictable) / 6 months + $5,000 (summary)
Since cannabis legalization in 2018, simple possession within the legal limits is not an offence. Over-limit, illicit, or public-plant possession remains a hybrid offence. Because it is punishable by indictment, IRPA s.36(3)(a) treats it as indictable, so a conviction can create criminality inadmissibility under s.36(2). The maximum of five years less a day keeps it below the serious-criminality threshold of s.36(1).
Legal cannabis has limits, and this covers going past them, carrying more than 30 grams in public, holding cannabis bought outside the legal system, or having a flowering plant in public. The serious route carries 5 years less a day, just under the serious criminality line, so a conviction is ordinary criminality. The lighter route carries up to 6 months and a $5,000 fine.
