WD40

AFAIK this lens is metal construction.  Is there any distortion to the end of the lens, where the filter threads are?  If so, I don't think you stand any chance of removing the filter except by the saw-and-hammer method referenced previously.

If the lens threads are still perfectly round, you might try carefully applying a little WD40 -- although not directly from the spray can, or you'll end up with oil everywhere.  Leave it to work for an hour or so, and then see if you can shift the filter with a thick rubber glove.  Perhaps tape the broken glass first so that it doesn't drop out into your hand.

Actually I think the person who said to send the lens to Canon was right, but I write this as an inveterate tinkerer who doesn't always do the right thing.
