Currently 209 cranes up on the spreadsheet which is fairly up to date, I believe that's a record so far.
The mega projects have really contributed to this number, currently there are 34 cranes serving the largest five projects; Oakridge (12), Richmond Centre (6), Southgate (6), Gilmore (5), and the Broadway Subway (5).
We're going to lose a few soon and might not make it to 210 so I figure a screenshot is in order.
