According to the Toronto Star, GM has pulled the ads, and has apologized. The ads were done by McLaren McCann, who did the 1999 series of ads trashing transit as well. GM claims head office never signed off on the series, and they are unsure what, if any, sign off process was followed.

Speaking as someone who works in advertising, I have a hard time believing this all happened without sign-off, but at least the blasted ads are down.
