In the application for funding, conditions are spelled out for preferred placements that seem very good. I think they got expert consulting. There's no Ontario manufacturer of charging stations afaik, so no rules favoring one approach over another. One peculiar clause though was requiring proposals for L3 funding be for units taking 480 volt input. Maybe they don't know that most utilities in Ontario are going to provide 600V or 208V and DCQC stations are available that are 600V or 208V compatible and save hosts from having to install extra transformers.
Uh oh... Sounds like maybe a particular manufacturer got that slid in...
Or maybe a more plausible explanation is that they blindly followed otherwise good recommendations from an American source, and they don't know that Ontario utilities mostly supply 600V.
Either way not reassuring.
