The building at 11th Avenue and Hamilton Street was originally the Pioneer Trust Building. Their sign was on the top of the building for a very short time before the business collapsed (bankruptcy) in 1985. At the time, it was the "largest financial failure in Saskatchewan's history". I have attached a link to the story from Macleans's magazine, if you want to read about Pioneer's demise.
After Pioneer Trust, it became the Canada Trust Building, and then Conexus. I'm curious if an illuminated HSBC logo will go on top of this building.

As for the signage removed from the top of Hill Tower I, I have a feeling that they will be replacing it with glass to match the rest of the building. Harvard has changed those signs a few times as well, from Continental Bank, to Lloyd's Bank, to HSBC, and now, nothing. The three openings were designed to be the size of six of the glass panels (per sign) used on the towers, in case they decided to no longer have signs up there, as is now the case. They have painted the steelwork dark gray just so the absence of any signs isn't as noticeable on first glance, or from a distance.
