Well the debacle that occured here in Montreal was that Petrys wife and 4 kids were living in Michigan, and (one was a newborn), and the border was difficult to cross last year.
It wasn't all that dissimilar to why Duncan Keith wanted to move to Alberta.
It didn't help that the Montreal hooligans went after Petry's wife and were incredibly hostile, and dogpiled on her any chance they could.
Her time in Montreal was well documented on her social media:
That can't feel good.

"It’s a bittersweet goodbye for our family," she says about trade to Pittsburgh. "We will go out with gratitude & love for the time we had."

So no.. Petry won't come back to Edmonton for the same reasons he wanted to leave Montreal.
