Cosa Nostra News article states:

That there are 3 families in Hamilton
Two of them are tied to American LCN

Obviously Bonnano and Todaro...
The third tied to the Rizzuto's the Mustiano Family

The two are taking out the Mustiano Family for two reasons:

1) Pay back
2) Take advantage of the situation

The Violios we know are Todaro family...

It looks like the picture is starting to come together up north

The Rizzuto's and their allies figured they didn't need American LCN backing....

That was a big mistake

Mustiano's rode the Rizzuto's coat tails, now that they are out of power they have no backing...

They are done

You see the Bananno's having making ceremonies in canada now and they are getting indicted with the Violio's and Gambino's....
