Is it acceptable to use a ground wire from one outlet to ground another?
You have two things going on here:


The superintendent's repair may or may not be acceptable -- if he used a bare or green wire, or single conductor MC cable (unlikely), it can be considered OK in jurisdictions that have adopted the 2014 NEC (you'll have to check to see if the Canadians have caught up to this change).
Do you have a tube-type TV? If so, you have an objectionable current flowing on the superintendent's ground wire, which is causing magnetic field emission which is interfering with your TV.  I'd have the superintendent pull the outlet(s) that test as properly grounded and check for a "bootleg ground" jumper between neutral and ground; trying to use the "ground donation" provisions in 250.130(C) point 4 with a bootleg ground jumper present could cause this as stray currents circulate through the EGC and bonding network back to the main ground/neutral bond jumper.
