Oh sorry Fuzzy, I didn't realize you were one of the few on the old Docsis 2 Extreme Plus plan. I think it was around October 2009 when the D3 speeds became available to me in London, but Toronto would've been sooner. It was also around that time they dropped the prices to what they are now. Before that it was $150 for Ultimate and I think $100 for Extreme Plus on Docsis 3, but my memory may be shoddy for that far back :P
You should definitely be able to get a free modem credit out of them and perhaps a discount. Just threaten to switch to someone else like Teksavvy or Bell and get connected to retentions.
For the record, the old Extreme Plus was somewhere between 15-18mbps, but the higher speeds you are seeing are just speedboost.
