Toronto Pearson is an international airport serving the greater Toronto area. It is one of the top 20 most busy airports in the world in terms of passenger traffic and aircraft movements. It is also the main hub for Air Canada, making it a common stopping point for those flying with Star Alliance (such as loyal United flyers like myself). I will also mention that the security staff here is as friendly as any airport Ive ever been to.
