They are testing electric buses with CUTRIC. I highly doubt that an agency with zero FCEV experience and no infrastructure to produce hydrogen is really going to be taking on hydrogen buses either. I actually have doubts that even MiWay will take on hydrogen buses beyond their little pilot. There's a whole host of reasons.
1) Economies of scale. Metrolinx is supposed to do group buys for the transit agencies in the region. And with the large ones going electric, the smaller one benefit being part of a larger order.
2) Limited HFCEV bus infrastructure and experience in the region. MiWay is the only agency in the country that is going to test hydrogen buses. And that was largely due to a previous
unique scheme of a local cement maker providing them hydrogen as part of an offset plan. CUTRIC is supporting the trial to get data on performance and costs. But this is not in any way scalable in any timeframe relevant to the other agencies in the region.
3) Local industry. There's electric bus manufacturing in the GTA. Brampton itself has a New Flyer parts centre and a growing auto electrification sector (rumoured to be contender for Chrysler EV plant).
I don't think Brampton's politicians and city staff can ignore all this and just jump in on random trials.
Also where did you get the idea that Metrolinx is interested in Hydrogen buses? New Flyer now owns Alexander Dennis and they are making double decker electric buses, along with electric coach buses at MCI. GO is most certainly going that route now. Especially after they dropped hydrogen from rail electrification considerations too.

You are substantially overexaggerating the range difficulties. Especially with these buses that come with giant battery packs. Edmonton got their Proterra buses with massive 660 kWh battery packs. They don't seem to have struggles with range that I've heard of.
As battery cost go down, the cost to add battery capacity becomes far less of an issue. At say $200/kWh, adding a whopping 300 kWh (60-85% increase over the standard pack) is $60k, not a substantial increase on a million dollar bus. And certainly not enough to drive a consideration of alternative power systems like trolley wires. It's great for the systems that have trolley wires already to be able to buy buses with smaller packs and avoid under-used wire coverage expansion. But nobody is going out of their way to put up new wires. Strategically placed Oppchargers do just fine.
