The following is a brief summary of where liquor may be legally possessed and consumed in the province, and hence, in the park.
  • Possession and consumption of open liquor is permitted only in licensed premises, a residence, or private place. A public place is defined as a common area used by the public such as docks, picnic areas, shelters, etc. Within Thousand Islands National Park, a campsite or vessel is considered to be a “residence” provided the following conditions are met:

      • One member of the camping party must be in possession of a valid camping or oTENTik permit.
      • The campsite must be used for camping per se..
    • Vessel:
      • The vessel must contain facilities normally associated with a residence (beds, lavatories, cooking facilities, etc.)
      • The vessel must be used as a residence at the time.
      • The vessel must not be underway. It must be docked, moored, anchored or hard aground.
    • These conditions apply equally to all members of the camping party, vessel operators, and passengers.
  • Violations of the Liquor Licence Act may result in charges being laid. It should also be noted that a person commits and offence under the Criminal Code of Canada where he or she operates a vessel or has the care or control of a vessel, whether it is in motion or not, while their ability to operate the vessel is impaired by alcohol or drugs.
  • Liquor is defined by the Act as “spirits, wine, or beer or any combination thereof and includes any alcohol in a form appropriate for human consumption as a beverage alone or in combination with any other matter.”
