I just had my first Astra Zenica shot this morning at a shoppers drug mart walk-in! Thank you so much
@hdrolfe for posting the list of shoppers walk in sites and letting me know yesterday.

I had no idea that any walk-ins were available as not publicized at all in my area.
I drove through the snow storm, got to the pharmacy by 7:20am, waited in the line in the parking lot for 8am opening and got my shot by 9am. Over 70+ people in line in the parking lot. The pharmacist came out at 8am and took everyone's name and assigned them a return window for today as the health unit would not have permitted such a big gathering. I was in the first group allowed to enter the building for the shot.
Even though I had preregistered with shoppers on Sunday night, it wasn't needed. Unfortunately not given a second appointment and told either shoppers or the local health unit will send me a text when it is available to book. They had no idea when this would be.
All of the assigned shots would have been taken now for today. But my advice for anyone considering AZ and going to a shoppers walk-in clinic, is to show up at least 40 mins before the 8am walk in, dress warm for the weather and be prepared for a wait. I overheard that the people at the end of 70+ line were being assigned 3pm and later time slots. Walk-in closes at 4pm. Also overheard a shoppers pharmacy employee explaining that their shoppers online registration system failed for this part of the province so those shoppers pharmacies that had AZ were opening up quietly for walk-ins. No one in the line had an actual appointment. Everyone had heard from family, friends and on the grapevine that walk-ins were available.
Feeling a bit tired but understandable as extra early morning and snow storm drive. So happy to have my first shot. Would absolutely have preferred Moderna or Pfizer but with our shortages, esp in rural Ontario, that would likely have taken many more weeks if not longer.
The Boards and DIS'rs are a wonderful resource and community!
