Duke Tower Kitchener | 39 fl | completed

[skyrise32]

The crane isn't nearly tall enough to do the whole building, so either it gets extended later or it's the kind that can jack itself up as construction progresses.

Maybe it jacks itself? I never seen an internal crane before...though doing a little research, it showed the particularly taller buildings are sometimes built this way.

Yes this crane will lift itself within the building as it goes up. You can see the hydraulic jacks used for this within the first tower section.
