The law states that it is illegal to have ANY marijuana in your possession, but with that said, the court would probably throw it or charge you with a fine.
This law dates back 25 years, the court is more interested in LARG grow ops then the little guy. Then again it is up to the judge and how he/ she feels that day, the minimum can be 6 month in jail to 5 years in jail.
From 6 to 200 plants can be 1 year to as much as 7 year sentence. I just read this that's how I know
Is possession of marijuana a criminal offense?
Yes. Possession of marijuana is a criminal offense under the Controlled Drugs and Substances Act (available at laws.justice.gc.ca - click on English, then on Consolidated Acts, then on C, and then scroll down to the Act). You dont have to own the marijuana you just have to have, or possess, it. There are medical exceptions. If you are charged with possession of marijuana, you should speak to a lawyer.
