As of May 7, 2012 the University of Toronto wireless network no longer uses a "quota" system.
This previously limited users to 1-2GB of upload/download data per week.
Whether one connects via UTORwin, UofT, or Eduroam...there is no longer a quota. This includes both wired and wireless connections to the network.
There has never been a quota on public or staff workstations. So there is no scenario where this restriction applies.
