Summer 2011 is possible. The building is 17 storeys so it won't take long once it hits ground level.
I suspect that it will be a bit later than Summer, 2011. Excavation has not yet been completed - it is still underway. I believe the timeline will go something like this (my guesses), starting from now:
1. Completion of excavation, building footings, install crane - six weeks, to end of April
2. Basement - garage levels, lockers, building services,up to grade etc. four months, May to August
3. Ground Floor - non standard forming - one month, September
4. Second Floor, set up of first of typical floors - one month, October
5. Typical Floors - 2 through 17, four months, November to February 2011
6. Mechanical penthouse and roof structure - building topped off - one month, March 2011
7. Completion of building systems after topping off, electrical, mechanical, life safety required for occupancy, plus complete construction of lower floor suites - minimum six months, more likely to be eight months, in other words, sometime around November 2011.
Just based on observing other buildings being built in Toronto, but that is what I would expect.
