(Hard to see the screen shot, but the URL is www.amritmangat.ca, and the page says that it's a Liberal Party of Ontario page and that it's under construction.)
Found this morning, the website appears to offer final and full confirmation that Amrit Mangat is a Liberal candidate.
We're told she's the Liberal candidate for Mississauga-Brampton South, but that's not clear from her website.
Now we just have to find out who this mystery woman is.
