I've always had a soft spot for the pavilions on the Islands – I love the low brown brick and the concrete lily-pads. Also, the carousel café building on Centre Island.
Also, a shout out to the little modernist pavilion attached to the front of Knox Presbyterian church at Spadina and Harbord, which is I think not long for this world, but I've always thought was quite charming:
Weston Centre is one of my favourite buildings in the city, and it is definitely not well recognized. Most people outside this forum probably wouldn't even place it in Toronto. The shape, cladding, atrium all form a really unique looking structure. I wish those 4 structures on the ground floor were not built, and the building's unique atrium could've been more visible (and also placed at ground level, rather than being elevated).
I had a job interview in that building years ago; if memory serves, the elevators were Death Star chic: black granite and red LEDs.Some great late-70s style.
