For the past couple of years, Showcase has had the episodes on the Sunday, following the US episode airing, (in essence about 4 days behind, which wasn't bad at all).
However, I have e-mailed Showcase and they sent me a canned response with a take a look at our schedule slap...and unfortunately when I look at their schedule...it's not there this year.
This is a very disappointing development as Rescue Me is an awesome TV show...enhanced by it being aired when nothing much else is on.
