The second report is out and the big difference is the commission backed off on merging Outremont and Mont-Royal. That is what happens sometimes, people oppose so the commission leave them alone and instead look elsewhere and those affected don't have the chance to speak at public hearings.
So in Montreal it's Sainte-Marie Saint-Jacques that will disappear. Westmount is taken from what was Westmount-Saint-Louis to go to NDG to become Westmount-Notre-Dame de-Grāce. The rest of Westmount-St-Louis becomes Ville-Marie and includes most of what was Saintr-Marie-Saint-Jacques.
The part north of Sherbrooke Street in the former Sainte-Marie - Saint-Jacques goes to join Mercier and what is east of De Lorimier (Jacques Cartier bridge) is put in Hochelaga -Maisonneuve.
I will try a direct link to the riding map:

QS would be the most affected here no? SMSJ they only barely won, but now Hochelaga-Maisonneuve which they were only 1000 votes or so away from winning becomes more winnable, gaining a huge chunk of polls that QS won.
Ville Marie is now dominated by the Liberals thanks to the western portion now, likely a Liberal win unless QS can find a strong candidate that can win over Progressive Liberals (I don't think that's Masse)
