I personally don't like the plan of phasing out River hippo, Indian rhino and Olive baboon, b/c they are charismatic animals that lots of visitors would like to spend time on watching them. But abandoning megafaunas seems become popular in recent days, so this might be an excuse for phasing out hippo and rhino. Baboon is one of the few species you can see in the Savanna during winter times, I don't get the reason why the Zoo wants to abandon baboons.
Switch the Australasia pavilion to the Canadian pavilion?? What species do you guys think can fulfill this pavilion then? Due to the high Latitude, Canada doesn't have that diverse amphibian and reptiles species. I feel that pavilion gonna be pretty boring, what about making it to North American pavilion? So that you can have much more diverse choices from the Sonora-Mojave desert and Florida Everglades wetlands fauna.
I do agree with
@Esox 's idea that Trt Zoo should have more cold-tolerant species in outdoor exhibits, they really need to put more effort into Canadian Domain and Eurasia. These two sections have the fewest visitors to come, the Domain can blame the big hillside it locates, while Eurasia is just not attractive enough to visitors.
Golden Snub-nosed Monkeys
Golden snub-nosed monkeys are one of few cold-tolerant non-human primates, but forget about them, China doesn't want to export them. Japanese macaque could be a reasonable choice, Calgary and St-Felicien having them currently.
Here are my suggestions:
Eurasia:
Japanese macaque: people like to watch a group of monkeys, watch them climbing, playing, and interacting with each other. Japanese macaques can be on display for entire year and there are some other Canadian zoos currently having them, so it shouldn't be hard to obtain them.
Dholes: it is quite embarrassing that Toronto zoo only has one canid species currently, the Arctic wolf. Visitors may recognize them as wolves, but that means Dholes can attract people's attention b/c many zoo visitors like to see wolves.
Amur leopard: big cat is typical eye attractors, Snow leopard is shy and often doesn't show up, Amur leopards may give visitors more opportunities to see them. But I am not talking about replacing the Snow leopard, since Trt Zoo gonna say goodbye to Clouded leopard, it make sense to add another Asiatic big cat.
Takin: since Chamois, Barbary sheep and Mouflons are in list of phase out, we need some new hoofed mammals, Takin is a good choice.
Golden pheasant: beautiful birds can also attract visitors' attention, and the Eurasia needs bird that hardy in cold. The Golden pheasant can satisfy both requirements.
Canadian Domain:
Snowy owl: the reason why Crystal is phased out is b/c the light and flash of Terra Lumina make her stressed, then we can place the Snowy owl in other section, like Canadian Domain.
American black bear: As
@TZFan mentions, it is almost impossible for Trt Zoo to obtain Asiatic black bear, then we may seek for two rescued orphans of American black bears, b/c bears are always charismatic to visitors. Even though the overall number of visitors in the Canadian domain is few, we still can see many visitors assemble to watch Grizzly bears.
North American porcupine: they are quite adorable, and not hard to obtain. Actually one keeper of Domain told me she really wants to have porcupine, and she recommended me to send request to Zoo via email b/c the Zoo is more likely to accept the suggestion from visitors rather than keepers.
I personally also like Great grey owl and Fisher, but they may be hard to happen.
Tundra Trek:
Currently two exhibits in TT are empty, how should we fulfill them? Some people talk about Wolverines and Walrus, almost all the Wolverines in captivity are Eurasian, that means we have to import from Europe, it is already hard to transfer not-small mammal over the ocean, don't mention the Pandemic makes the transfer much more difficult. Walrus is very expensive to be kept, b/c they consume great amounts of shells. The Zoo is facing financial shortage, so Walrus is not a wise plan for the zoo in current situation. I like Arctic fox, but Toronto Zoo has already showed us several times that they are incapable of keeping this small cutie at all.
For Arctic fox exhibit, my suggestion is retrofiting it to an aviary with pond, and have King eider and Harlequin ducks. For Snowy owl's exhibit, my suggestion would be Willow ptarmigan, we don't have many choice for this, Gyrfalcon sounds very cool, but hard to happen.
Having Musk ox mixed with Caribous sound great, that Caribou's exhibit should be wide enough.
Additionally, I am curious that how costly for Toronto Zoo to keep Koalas? Since Koalas are fed on Eucalyptus leaves only. I know Toronto Zoo used to keep Koalas three times, but none of them stayed in the zoo for even one year.
