This isn’t exactly a canon reference, but the “Noonien-Singh Center” was clearly filmed at the Royal Ontario Museum - both the interior and exterior. It’s such a distinct building that it really stood out.
Yeah, that was definitely actually Toronto. The big area they’re wandering around in at the start is Yonge-Dundas Square, and I’m pretty sure this is the clothing store they stole from. The “Noonien-Singh Center” at the end was actually the Royal Ontario Museum - both the interior and exterior.
Kinda weird seeing Star Trek characters actually wandering around in an area I know decently well.
