From the website:
"The Toronto Zoo is set in the beautiful Rouge Valley. The Main Entrance is located on Meadowvale Road, Toronto, north of Highway 401 (Exit #389 eastbound and westbound). The Zoo is accessible by car and public transit.
The Zoo is divided into seven zoogeographic regions: Indo-Malaya, Africa, the Americas, Australasia, Eurasia, Canadian Domain and the Tundra Trek. Animals are displayed indoors in tropical pavilions and outdoors in naturalistic environments, with viewing at many levels."
