That's certainly how I read it, especially given what Stac has said before on Twitter.
I have no experience with deploying this type of software, but why would the programmers being based in Canada make software updates more complicated? With a system this big I would have thought that the software company would do their programming in-house with simulated data sets before sending an engineer to install and test it. So in terms of the programming, distance from the stadium would not be an issue. Happy to be informed.
Johnson Controls is a multinational company who merged with Tyco in 2016.
It could be that the panel installed for the stadium has it's R&D team based in Canada.
