I suspect some of the BC members can provide the exact dates, but the London drugs and Bentall opened in November 2017 and I have strips from late December. There is a new Kiosk in a Shoppers drugmart in downtown Toronto opened 2 November 2017 as number 105929. There were 2 additional Toronto kiosks that were supposed to open in Nov 2017. One at the TD Centre has been cancelled. Another machine also at a Shoppers Drugmart in downtown Toronto is delayed to this coming June (tentatively). So there are 7 active kiosks at this time. Hope this helps.
The Permanent stamps from what I can tell are the same as they were before. The change is just the printing of the rate. The only reason to collect strips of 4 and include the Permanent is if you want strips for all values showing all the rates. Your printed sales slip from the kiosk whould show the new price of the P stamp.
