Of course they won't squeal like the old ones, since they're not 25-35 years old. Let's wait till 2035-2040 and see how they bad things get.
The squealing I'm referring to comes from the non-tangent angle of the wheel to rail interface. The worse that angle is, the worse squealing will be at low speeds on tight corners. It has nothing to do with the age of the vehicle and would not increase over time. Fixed-bogie trams need a larger wheelbase otherwise the ride quality suffers. It's a trade off in design.
However, as others have pointed out, it is not much of an issue I guess (it was in Gold Coast with their new FLEXITY 2 trams, which use the same core architecture), so something has been done in Toronto to mitigate the noise.
