"I do seem to recall reading that there had once been a plan for a north wing but they lost out on the land at some point in time and the extension to the east was their only option."

The only buildings that I remember being on the north side of Piper Street were The Toronto Club, (s/e corner of Wellington & York) and
The Royal York's, if indeed it was The Royal York's own garage, to it's east. The Toronto Club would not want to move, so that would leave
a parking problem for the hotel during construction. This would later be limited as "redevelopment" provided more parking space, especially
when the garage itself was sold with the East Wing already having been built beforehand.
