Anemic attempt at re-greening - it looked more like the focus is on the planters with some anonymous vegetation added for colour. If they think this is going to make the place more lively, they need to think again.

I would love to see the actual trees back, but I get that the main corridor is actually capacity constrained, and that may not be on for that reason alone, besides which I'm sure the tree roots caused issues over time. (not an excuse, its very manageable but you have to know what you're doing.)
That said, let me offer an alternative greening choice that I think would add value, has no roots issues and could be quite dramatic.
Vines/plants that spill like them (hang down from planter, rather than growing up) attached to base of the second floor and allowing them to frame the main arcade on the south side.
They can be auto-watered, and you can double-hull the planters to minimize any risk of leaks.

You can actually see a hint of this idea in the Eaton Centre's former greenery as illustrated in
@nightstreak 's photos:
Just imagine that coming down towards level one constantly.
Then use the planters to have complimentary lighter coloured ferns on their edge, and then a bold, bright plant in the middle. I'd consider changing the middle plants out seasonally, and actually selling them.
