Secondly, my understanding is that all cars brought into indoor locations like this have to be drained of all fuels and volatiles as part of the fire code. If this is not the case, big auto shows like the one in Toronto are major disasters waiting to happen! I was at a large industry show a couple of years ago in San Diego (not a car show) and they brought in a Fisker Karma to display. I was told by the vendor at the particular booth about all of the things they had to do to the car to get it indoors, including the fuel draining requirement. I would have to assume similar rules exist in Canada.
This sounds like a HUGE oversight and a very big bullet dodged.
