No need to light the "Lat-Signal" I follow most of the main threads daily.
I could do a render with the upper picture that would show L-Tower and the proposed 45 Bay Street but it would probably disappoint you. Especially for 45 Bay, because it would be partially hidden by the CN Tower. See the spotlights from Air Canada Center? Follow them down to their focal point. Now that is approximately where 45 Bay would stand.
As for L-Tower... If you know which building is the Bay-Wellington Tower of Brookfield place then you will know L-Tower's apparent height from this vantage point. As well, it will be almost equidistant from the TD Canada Trust Tower to the South as Bay Wellington is to its North and half hidden by Simcoe Place in the foreground.
Does any of that make sense, or do I still have to do the render? LOL
