We all talk about the tallest buildings, but I'm curious, what's the deepest building? Not including subways (York Mills Station) or tunnels, what's the deepest building?

Wonder what the average number of levels underground is here in Toronto and what's considered 'deep'.

The depth of the foundation has nothing to do with the number of occupiable floors below-grade.

That said, RoCP is fairly deep (6 or 7 storeys, I believe). I recall Festival Tower also seeming to have a very deep excavation.
 
A quick wiki search claims that Scotia Plaza is the deepest "The excavation reached a depth of 110 ft (33.5 m) which is the deepest excavation for a building in Canada's history." - wikipedia. Take that as you will. Shangri-La was the second deepest.

Cool!
 
1. 110ft Scotia Plaza
2. 101ft Shangri-la
3. ??? ROCP or perhaps RBP - there are rumors of deep sub-basement levels

To quote myself, I was wondering if any more recent projects in Toronto ever surpassing Scotia Plaza in this respect?

I'm bumping this because I just came across this video about 1515 Alberni in Vancouver:
The video was just released 4 weeks ago though apparently this excavation happened one and a half years ago to very little fan fair.

The excavation depth for that project was noted as being an impressive 120 feet/36.5m, with some parts possibly reaching 133ft/40.5m! It was said to be the deepest in Vancouver's history, and in probably all of Canada's as well(for a highrise building). The only Toronto project I can think of that was deeper is The Well, but that was only for the Geothermal storage tanks and not the building envelope, as was the case with "Fifteen Fifteen" as they call it in BC.
