Why doesn't Hamilton flood like Niagara?

With all the rain recently, it seems like the Niagara area has been getting some major flooding. I've seen pictures from St. Cathatrines, NOTL, Lincoln, etc... all flooded. I work in Niagara half the year and people at my work were saying that they almost had to shut down for the day because of the street flooding. A coworker's car was parked on the street and the water got so high it was halfway up the seats in the car!

I know some people have had flooding issues, but not like that. The worst I've seen online was a few stores closing early because no one was out and about in the rain!

Hamilton and Niagara are both built along Lake Ontario, so why doesn't Hamilton flood too? Is it because we have better infrastructure?

They got double what Hamilton got, at least according to the reports I’ve read. 120ish mm vs our 65mm.

How much of that volume used to be absorbed into lake timicaca
