If you spend enough time in downtown Toronto, chances are you've walked by an adorable little sphere adorned with a windshield, lights and distinctive green GO Transit livery stationed at the southwest corner of York St. and Bremner Blvd. 

The futuristic-looking installation, which has been sitting outside the office tower at 16 York St. since November, has puzzled many passersby in the seven months since it was erected. 

But while many have been left wondering what it is, residents — for the most part — seem to agree on one thing: it's undeniably adorable. 

@GOtransit Cute! 😀

Fortunately, the sphere is actually an art installation project with Cadillac Fairview and the city, and it's here to stay permanently, according to Metrolinx spokesperson Anne Marie Aikins. 

Mystery solved. It’s a fantastic art installation project with Cadillac Fairview & city. Artist wanted to reflect the rail history near the building. Will be amazing when done. https://t.co/qAUIR94QrM pic.twitter.com/ZV1fA2fWVD

The piece was created by Lars Fisk, an artist specializing in spherical installations such as this one. 

When he was in the process of building it, Aikins said he told her he wanted to reflect on the rail history near the building and, at the same time, pay respects to its neighbour, Union Station. 

Inside the structure is a caboose ball, according to Aikins. 

She called the installation a "delightful surprise" and said, "the art stops people and dogs in their tracks."
