He was a pending UFA, but when Jeff Petry was traded to Montreal, him and his wife absolutely adored it. They really embraced the city and everything it had to offer and Petry was about as proud as anybody could be to wear that jersey and represent the city.
Obviously the tight pandemic rules made things extremely difficult for them, especially his wife to the point where they asked for a trade.
Toffoli signed with the Habs (He's Canadian) and his wife (although has a French name) is absolutely American and from California. They loved the city as well and were sad to leave. Every time the Devils play in Montreal his wife posts pictures and videos of the city.
Honestly it really depends on what you're looking for. If your only criteria is low taxes and year 'round mild weather, then Montreal ain't for you. ...But if you enjoy culture, amazing food, great architecture, cool vibe and and full hockey experience, then Montreal is one of the best markets in the NHL.
To each their own.
