I am waiting for Crystal Blu, Uptown, 77 Charles, Minto St Thomas, 4 Seasons 1&2, 1 Bedford, X, Milan, and more to make an appearance on the skyline soon. (I can see Minto Sky from mpov as well.)
To respond to dventura about topping off in June.
if they're on 45 now, 46 next week (done May 30)
then they have the mech penthouse for which they can't use their typical forms so the carpenters will have to build those "custom" forms for the 47th floor. This could take the best part of 2 weeks and then they still need to build the roof which again will be with custom forms... another 2 weeks. And for all I know there might even be an intermediate level in the mech penthouse before the roof...
So I think July is more realistic than June. Maybe if you show up on site with tim hortons coffee and tim bits then they'll go at it a bit faster!
