For some, Toronto's public libraries are something akin to civic sanctuaries, a place for community gatherings and learning.

For five-year-old Jackson Ryan Bennett and his father, Lanrick Bennett Jr., they're places of pilgrimage as they've embarked on a mission to visit all 100 of the city's libraries.

Dubbing the quest #JacksLibraryTour on Twitter, the idea first sprung up through a book they owned that included illustrations of Toronto's libraries by Daniel Rotsztain.

"I brought it home and showed it to Jack and he wanted to go to the Fort York library," the elder Bennett told CBC's Metro Morning. "I thought, 'nice and easy, we'll pop over there, take a look at it.' [We] had a fun time and went home and he was like, "I want to see the rest." And there were 99 more of these to see."

During the interview, young Jackson disputed his father's account of the genesis of their journey.

"Daddy, it wasn't like that," he said. "It was you."

The Bennetts have visited 28 libraries so far, reaching each of them via public transit.

They've been to Scarborough, and they've visited the libraries along Jane Street, Queen Street, College Street and St. Clair Avenue.

Jackson said he mostly likes to watch videos when he goes to the library, but at one location "there was only books."

So he checked out his favourite: Transformers Rescue Bots.

They spend two hours at each branch, walking around and reading and checking out books.

Lanrick's favourites so far are the Runnymede and Riverdale libraries.

But his favourite part of the project is the chance to spend time with his son.

"I work Monday to Friday like many fathers," Bennett said.

"You've got to find time to spend with your kids."
