I find both Kingsway and Princess Gardens to be inappropriate names for the station.
Princess Gardens sounds really nice, I'll not dispute that, but it is not a location that is known to most people - I am a lifelong road geek, map enthusiast, and I know the city well, and have never heard the locale referred to as such before. It appears neither in any street atlas of Toronto I have ever seen, nor is it shown on the city of Toronto's neighbourhood map - the area is filed under "Princess-Rosethorn", itself a fairly arcane designation.
The Kingsway is almost half a kilometre from the proposed station site and is about as helpful to wayfinding as calling St. Clair West station Vaughan.
Nay, the only logical name for the station is Kipling North.
