What would that baseline be? Also, I'm pretty sure Kuala Lumpur bought MK IIIs that were built in Ontario.
See "post-opening", which I can promise wasn't edited in since you quoted it. And my later edit that 3 of 5 didn't even use Canadian-built trains ever.
What would that baseline be? [...] What would you say is outdated about them? I find those door switches annoying to, but that seems like a really minor issue, and appears to be more of a supplier problem.
They're poor quality and/or outdated, not to mention expensive compared to even European-built trains (see below). For GO specifically, I am comparing GO trains with intercity and commuter rail in East Asia (as well as NS in the Netherlands, which also run bi-levels). Someone else chime in here. Euro S-bahn-y, commuter, and intercity trains tend to be much nicer than GO trains that aren't even truly walk-through right... But again, the GO bi-levels are a legacy holdover, and changing to completely new stock would be expensive.
If we're doing would've should've could've: Toronto Rocket's should've been built with lighter, (cheaper?) materials (less stainless steel, more aluminum), larger diameter wheels, with colour LCD screens, and better integrated A/C units (why is the ceiling so low), among other things. Having been on metro rolling stock of the same or earlier era, the Toronto Rockets leave a lot to be desired:

I previously compared Finch West's Citadis Spirit to Paris T9's Citadis 405. 30% more money for less reliable (see ongoing OTrain disaster), worse-turning, LCD-screenless, uglier trams with narrower gangways, and somehow one less door (7 instead of 8 per side).
But there is no way to say either way if this is due to being manufactured in North America. Bogie design is probably European. Though I'm not entirely sure if they were manufactured in Europe.
The bogie designs for the Citadis Spirit are uniquely North American, at least
nominally. The Citadis bogies are called Iponam aka Ixège Pour North America. For the Freedom's case, the bogies are almost certainly not unique to NA. However, even if we forget the Euro-Flexity Outlooks from the early 2000s, the first Flexity 2 entered service in 2012, versus 2019 for the Freedom, and 2026 for Eglinton. Low floor bogies capable of higher yaw angles (i.e. better turning) now exist. Poorly turning bogies are the core problem with low-floor trams. That is why I say Canadian-built rolling stock is outdated.
The Freedoms are not that different from the Outlooks introduced 12 years ago. Don't forget the lack of LCD screens.
And in Eglinton's case, the reliability appears to be poor too. The "ongoing issue [...] when they operate over 60" is not the first time Eglinton train reliability has been questioned. Cheap

. So what kind of value-for-money did we get here?
