I think this is just sort of a start to an increasing number of home auctions.
In Australia home sale auctions are very popular. I went to one the last time I was there, and often they do get very good prices. They're also done with very few private visits, mainly open houses, which saves time for the Realtor.
I don't know how frustrating/difficult this must be, but what you're saying seems to show that Winnepeg at least is headed in the home auction direction.
