‘involving’ is a weasel word. If a building is on fire and a battery catches fire and makes it worse, that’s ‘involving’. But that doesn’t mean the battery is to blame. It’s just another accelerant.

Is this not a tiny, super fraction of a number? The average household probably has 10x lithium batteries around in various things.

Toronto Fire Services (TFS) told CBC Toronto that it has responded to 47 fires involving lithium ion batteries this year, 10 of which took place in residential high-rises.

Without clarification that this is specifically related to EVs, this statistic is worthless. I have 7 different devices involving lithium-ion batteries in front of me right now, and none of them are vehicles.
