Not more that Montreal imo but their core is weaker

Montreal Canadiens
Wins Added: 0.5 wins
Salary Added: $12.3 million
In: Josh Anderson, Jake Allen, Tyler Toffoli, Joel Edmundson
Out: Max Domi
This may feel like a shockingly low spot for the Canadiens, so it’s worth explaining what the model sees here for a team that is spending $12.3 million to earn an extra 0.5 wins.
For starters, the Jake Allen and Joel Edmundson additions don’t move the needle. In Allen’s case, the model doesn’t account for the fact that Carey Price will likely perform better from being more well-rested. As for Edmundson, he’s not viewed fondly by the model and pushes arguably stronger options like Brett Kulak and Victor Mete down the depth chart.
Up front, both Tyler Toffoli and Josh Anderson grade out as top-six calibre forwards, but neither project to be as good as Max Domi. Together they are, but the Canadiens were already relatively deep at wing meaning the two moves offer diminishing returns. In any sense, the forward group is indeed stronger and that’s where the 0.5 extra wins comes from.
*******************
Edmonton Oilers
Wins Added: 1.0 wins
Salary Added: $4.4 million
In: Tyson Barrie, Kyle Turris
Out: Matt Benning, Andreas Athanasiou, Riley Sheahan
The Oilers aren’t on this side of the offseason ledger often, but they did well this fall. With Oscar Klefbom injured, Tyson Barrie is a strong add at a reasonable price as a guy who can move the puck up ice and quarterback the top unit power play. The Oilers are short on puck-movers on the back end and Barrie’s presence should make life a little more fun for the team’s talented forwards. Kyle Turris isn’t what he once was but the potential for a bounce-back campaign is alluring.
The issue with both is that neither does much to solve the team’s defensive issues. In fact, they probably add to it. Regardless, both remain a net positive thanks to their offensive contributions and the Oilers should be better positioned to be a playoff team next season because of it.

And since then Edmonton has added Kahun who grades out at +1.0 wins:
