Ontario Cannabis Home-Grow Rules: Four Plants per Residence
Ontario's four-plant rule
Ontario says people aged 19 or older may grow up to four cannabis plants per residence--not four per adult--when the plants are for personal use, the starting material was bought from the Ontario Cannabis Store or an authorized retail store, and growing is not forbidden by the lease agreement or condo rules. This is the province's stated baseline, not a conclusion about whether a specific address is eligible.
Conditions before planting
Check each condition against your situation: Are you at least 19? Is the grow for personal use? Can you document that the seeds or plants came from the OCS or an authorized retailer? Do your lease and condo documents permit growing? If you rent or live in a condominium, read the actual written terms rather than assuming that provincial cannabis legality overrides them.
Safety and local checks
Health Canada says adults growing for non-medical purposes must follow relevant provincial, territorial and municipal laws. It specifically lists zoning, fire safety, electrical safety, inspection and remediation requirements as possible local rules; ask the municipality about the property address. Use legal starting material, keep cannabis locked away from children and pets, and do not use explosive or highly flammable organic solvents to make products at home.
