Fred,
Well, I'm not saying that it's always close to 500,000 people. Like I said, on average, we can expect anywhere between 250,000-350,000 people each show. But I'm more than certain that, at times, it can get between the 400,000-500,000 range, especially taking different aspects into consideration.
Now, like you and all of us here, we are huge fanatics of the competition and it would be great to have high figures, but if you think about it and consider popular spots around the area, it comes out to lots of people.
The sources that I went through gave similar figures to that of this site, so it's clear that there are lots of people in surrounding areas. If you come on Notre-Dame and De Lorimier, there alone has tons of people. Other adjacent streets have tons of people, too. I know that because I've been going on Notre-Dame and De Lorimier for 14-15 years.
I know it easy to think that 500,000 is a big over-estimation and yes, it is approximately 1/6 of the population of Montreal, but it's an idea of what potential nights can be like, but not all the time. To be honest, my uncle said the same thing as you did, but I don't blame him. If I had to give a safe figure per display, assuming the weather is nice, I would say anywhere between 250,000-400,000, or 350,000.
Regards,
Trav.
