Hi Ali,this time of year almost any kind of owl could be seen in the city. Eastern Screech Owls are the most common nesting owl in the city of Toronto. A Boreal Owl sighting,would be more uncommon,but not unheard of. I know that an Owl Walk used to be held at Mount Pleasant Cemetary in early February each year. I have found Great Horned Owl feathers in MPC in the summer. That is right around the area U mentioned. Final opinion...of the 2 choices Id go with Screech Owl.
