Adam Jensen flies to Montreal in search of Katrina Sutherland, to help find his former team commander turned psychotic killer Quincy Durant. At her hotel room they are ambushed by several well-equipped attackers, led by Durant. Jensen nearly kills him after a fight, but he escapes. Jensen and Sutherland leave for Detroit soon after.
Although the Picus building is the only part of the city visited in Human Revolution, Eidos Montréal originally planned to have a large "Hub" level here, similar to Hengsha and Detroit. Although it was not as close to finalization as Upper Hengsha was before getting cut, some concept art and basic level design had already been discussed and appeared to be inspired by the Plateau Mont-Royal borough.
"It’s got very specific architecture called tri-plexes with twirling exterior staircases made of this old metal. It is very specific to Montreal. We’ve drawn concept art of how these streets would look in 20 to 30 years from now. We even tried them in game. Walking around them felt quite special – that architecture has never been in a game before… it was really cool."

Concept art reveals that a laboratory was considered for Montreal.
