A 7-year-old boy from Canada is coming to the Chattanooga work site for "Extreme Makeover: Home Edition," courtesy of the Make-A-Wish Foundation of East Tennessee.

Alex's wish is to see behind the scenes of "Extreme Makeover," his favorite TV show, according to a press release. He will be in town Wednesday.

Make-A-Wish grants wishes to children with life-threatening medical conditions, but the release does not say what Alex's medical problem is.
