Minto Spring is still being constructed, you are probably referring to the neighboring building "Minto Radiance". I have a couple of friends who live there so I've visited a few times. I think out of all the "newer" already constructed buildings in the area it is the nicest. Love the lobby especially, the amenity rooms are great too. Really liked my friend's unit too, but he had it professionally renovated so not sure what a standard unit looks like.
I would be weary of the impending construction to the west of it (Hullmark Centre complex), which will likely block some views of both Minto towers. But the construction might make units harder sells, so maybe some near term opportunities to get units in that complex for a better price than usual.
Also not sure what is included in the condo fees (maybe hyrdo exlcuded), but $0.51 PSF is the going rate for buildings in the area and definitely in line.
