I have done a lot of research into Kanawaki & Colt and I think it's entirely possible, but I don't know for sure. I haven't found any definitive proof, so unfortunately, I can't prove it.
With that being said, Colt was in Montreal spring of 1913 and Kanawaki opened with 15 holes that fall, and the full golf course opened in 1914. The golf course is routed in triangles, like Colt did at Hamilton, and the par 3, 17th feels like a Colt one shot hole.
Anthony's book mentions the long two shot holes feels like Colt, too.
My best guess as of now: Colt stopped by to help a very new Albert Murray given Kanawaki & Royal Montreal's relationship, and gave some direction. As of now, I can't officially prove it's a Colt.
FYI, Donald Ross renovated Kanawaki around 1920 and the club has buried that, so it's entirely possible.
