In Toronto, you are only allowed to cook or use a barbecue in a city park if you are using a permanently installed park barbecue or have obtained a specific permit for a portable unit. According to Municipal Code Chapter 608, the use of portable BBQs is generally prohibited without prior authorization to prevent fire hazards and damage to the grass. However, there are exceptions; for example, the Toronto Islands feature designated areas where you can bring your own charcoal BBQ without a permit for groups of fewer than 25 people (though propane units are strictly banned on the islands). For other major parks like High Park or Sunnybrook, you must reserve a designated picnic site that includes a fire pit or BBQ stand. If you are caught cooking in a non-designated area or without a permit, you could face fines from bylaw enforcement officers. Always check the signage at the specific park entrance, as rules can vary locally based on seasonal dry conditions and the specific amenities available at that location.
