Justin leaving Toronto Pearson Airport June 21 2010

He’s always on the go, and earlier today (June 21) Justin Bieber was spotted catching a flight at Toronto’s Pearson International Airport.

The “One Less Lonely Girl” singer looked to be in good spirits as he made his way through the terminal and went into the security checkpoint.

Last night, Justin was one of the big winners at the 2010 MuchMusic Video Awards in Toronto at MuchMusic World
