I stumbled across another forum that has a little more info about the discontinuation of Vaniqa in Canada. See
here
It also appears that some people have had discontinuation confirmation from the distibuting pharmacuetical company. So bye bye Vaniqa!
As for the Outback Steakhouse
I found
this statement on their website.

I feel for you. Years ago I felt the same way when they closed all the Olive Gardens. Thankfully I now live driving distance to few different locations so when I do get a hankering for their salad dressing, I can get it. It might take 6 hours, but hey it's better than not getting to go at all.
