Hey tboy:
Good points too... Actually, I did buy in the area because of local retail, but it was more because of the presence of small owner-operated shops than it was the ABSENCE of large big-boxes. There's something about owner operated shops that is much more appealing to me than big-boxes. I like strolling into shops and getting to know the owners - much better service. They actually know and and support the area - so there is a community feel to local shops.
Also, my purchases and buying patterns generally do not take me to malls or big-boxes. The exceptions are some clothes and electronics, but both are infrequent purchases.
Will Wal-Mart kill Queen Street East? More than likely not - however, I do support small retailers, and I think that Queen East is not firmly established yet, and I don't want anything in the area that could hurt some of them.
Anyhow, you're right about traffic - it will increase, but there are two kinds of increases. There's an organic increase because of natural population growth and a transit system that is virtually beyond repair. I can accept that. What I can't accept is something that is put into the neighbourhood that increases traffic beyond what is normal.
What I do agree with is that the current malls and big boxes do need a good swift kick in the ass. The HD is horrible, and Zellers barely has a pulse - but again since I don't shop at these places much anyhow, Wal-Mart won't make a difference. See, I think that most any HD and Zellers and Wal-Mart for that matter are horrible, regardless of where they are.
I think the ones in Leslieville are particularly bad because they're small and the demographics don't support the selection and availability at other stores.
Anyhow, if it comes, my two concerns are whether something could have been put there that would make better use of the space, and the traffic brought with it. To answer the original question - it won't lower property values and will not horribly impact the area, but my opinion leans towards not having it there.
Now - how about putting in 700,000 square foot red-light district there instead!
