Most of Ontario (Major centers but not all smaller towns) has been built out to 860 (not 1000) MHz. They could be upgrading the wiring if it's RG59 to RG6 say. Your presence may not be necessary if the management has the right to enter your suite for such instances... How old is your building - if 20+ years, then it was probably wired with RG59, which may not be adequate for newer services, especially in longer runs like apartments.

The new wiring would probably be just "to" the suite (a service box in your suite) and not "inside" the suite since those short runs are usually fine. If any filters were installed for basic cable customers, they may also require removal for any digital customers as they can sometimes cause issues with SDV. These are often located in a central location, but not always.

Perhaps some splitters needed replacing, or filters removed. It would have been nice to know exactly what they did. It's possible, for example, that the splitters were not rated highly enough for the current bandwidth, which usually affects the higher frequencies, many of which are used for the HD channels. There are also special splitters that are utilized for people with broadband connections where the loss on the drops can be tailored appropriately.
