Depends on the CRTC. A decision on this could be any day now, or could be sometime in January.
If the CRTC comes down against Rogers (hopefully!), I'm not sure how long it would take for the speeds to make it through to Teksavvy and other cable wholesalers.
For the long version, read through these:
