Bravo!!! Based on the crane's positions, I'm sure you're right that all 3 belong to 293 Kingsway. I still can't get over the fact that the right-most crane (the one pointing upwards) and 299 Campbell appear next to each other, although in fact they're at least 5 km apart as the crow flies. And the 3 cranes from the same project appear to stretch over such a huge distance. Never trust shots taken with telephoto lenses!
