If you think about Buffalo was/is a very important supply route from Canada
During Prohibition it was used for liquor and shortly thereafter as as drug route you have the family that is set up on both sides to smuggle whatever
That alone is HUGE
That route is how alot of the families in the US are getting their drugs shipped in.
Why would they ever give that up?
It looks like the Canadians have full control over that. Even in the 1990s it didn't seem like Buffalo was hugely involved in that drug/liquor route, although I could be wrong.
