Justin Bieber Drops $5 Mil On Canadian Mansion With Private Horse Track

Justin Bieber is one step closer to being a pro jockey ... dude just bought a crazy huge $5 MILLION mansion in Ontario, Canada with it's own private horse racing track.

The property is 101 ACRES -- a skosh smaller than the size of Vatican City (for real, look it up) -- and this place has it all!!!

Private lake access? Check. Two story temperature controlled wine room? Check. Private gym? Check. Heated floors? YOU KNOW BIEB'S GOT HEATED FLOORS!!

Oh, and did we mention ... the place has its own private equestrian facility with stables and a 5/8 mile race track!!!!

The living space is 9,000 square feet -- with 4 bedrooms, 6 baths, 3 fireplaces, game room and movie theater (obvi). It's also got a 3 car garage.

We're told Bieber closed on the place on Monday -- no word on when he plans on moving in ... but the sooner, the better.

Unclear if Bieber plans to make the home his main residence with fiancee Hailey Baldwin -- or just a place to get away and hang by the lake.

Either way, it's another baller piece of real estate Bieber can add to his portfolio.
