Essential zoo staff remained on-site during the closure to continue caring for the animals. During this closure, a baby Masai giraffe was born. The zoo re-opened as a drive-through experience beginning May 23, 2020, and expressed hope to fully re-open later in the year. The Toronto Zoo is divided up into seven different geographic regions. Each region showcases animals and plants from that area of the world. The Indo-Malayan area contains two pavilions that exhibit plants and animals from South and Southeast Asia. There are four outdoor exhibits in this area. Featured animals in this area include Indian rhinos, babirusa, Sumatran orangutans, Mandarin ducks, spiny turtles, rare Sumatran tigers, and various freshwater fish. The Malayan Woods Pavilion houses butterflies, whistling ducks, red-tailed green rat snakes, and clouded leopards. The former gaur exhibit is currently being reworked into a large outdoor orangutan enclosure that will allow further study of orangutan social behaviors. Opened in 1998, the African Savanna became the zoo's largest expansion in history. The African Savanna combined with the African Rainforest Pavilion encompasses most of the southern third of the zoo. The African Savanna featured species include white lions, Grévy's zebras, olive baboons, greater kudus, cheetahs, white rhinoceroses, river hippopotamuses, spotted hyenas, watusi cattle, African penguins and masai giraffe. The African Rainforest Pavilion holds the world's largest indoor gorilla exhibit, home to Charles, as well as dozens of other more sensitive African species, including meerkats, red river hogs, West African dwarf crocodiles, and pygmy hippopotamuses. The south side of the African Rainforest Pavilion underwent extensive renovations in 2009 and 2010, and opened in the spring of 2011. The south side of the pavilion is completely refurbished and showcases ring-tailed lemurs and Aldabra giant tortoises. The Canadian Domain is situated in the Rouge Valley. The Canadian Domain was built in accompaniment with the Canadian Domain Ride, which exhibited North American animals in their native environment. Featured species in this area include wood bison, moose, bald eagles, cougars, lynxes, raccoons, and grizzly bears. Due to the remote nature of the area, the Canadian Domain animals are slated to be moved onto the zoo's mainland in coming years.
