Conroy Pit and Bruce Pit are great but might be a little busy for a young puppy. Start with some place like Petsmart where all dogs are leashed and work up from there, look online for on and offleash parks in your area. Ottawa has several of each, some better then others.
It's probably best to scope them out beforehand before taking Draven with you
For non-specific set up play dates with suitable dogs either with family or friends, see if a nearby training centre has a socialization group, or even go back to your breeder for playtimes if they'll allow it
