I think that this Maglev train actually opens up a roadmap for the future of the Zoo. Concrete urban zoos have fallen out of favour and Toronto is in a unique position to provide an antidote to that. Our zoo is connected to our ravine system.
I'd like to see the Toronto Zoo become a series of naturalized animal habitats spread out throughout the Rouge National Park, connected by a silent Maglev. Rather than tickets to a place, visitors would purchase a pass that allows them use of the Maglev to travel between these habitats and to get off at viewing areas or just view animals from the train without getting off.
Humans would be put in the boxes, not the animals. Animals would roam "free" within their naturalized fenced off areas while the humans would be in glass boxes at the base of Maglev stations. Imagine elephants and giraffes roaming in large natural areas. Perhaps the more dangerous animals like big cats and gorillas would still need to be in more controlled environments with moats but many of the animals could roam in what would appear to be open areas with the Maglev flying over.
The main zoo grounds would be maintained as a welcome area with educational pavilions and interaction with small animals but most of the zoo would be naturalized and merged into the park.
I love the idea of treetop hotels in the valley. You could wake up in a treetop hotel within near reach of giraffes or go to sleep with monkeys in the trees. This has the potential to generate far more revenue than selling tickets does today, allowing limited access to the zoo to be free to the public from the trails in the periphery. People would still pay to ride the Maglev to easily tour all the exhibits with better views.
Whatever the case, the era of enclosed concrete zoos is coming to a close with millennials mounting online opposition to imprisoning animals in exhibits.
