I was curious about that so tried googling …. Canadian buses were - earlier models - I see years like 2018 - at least some were built in a new plant in Canada - part of the blame was lack of spare parts - part of the blame was limited range, especially in winter London buses - newer. I see years like 2024 - no real winter - I see articles about a new larger battery to fix range issues - appeared to have similar problems, including a major recall for fire risk Maybe London benefitted from newer models and doesn’t get as cold as canada
