From here:

Strictly Right sent out a press release earlier today to Canadian media with some rather startling news about the upcoming Mark Steyn speech in London, Ontario that we’re putting together. Mark Steyn will be speaking on November 1st in a speech entitled “Head for the Hills: Why everything in your world is doomed.” Apparently, London-area Muslims didn’t like that idea too much.

Due to capacity constraints at the University of Western Ontario, the original venue for the event, we had booked the London Convention Centre (LCC,) London’s premiere conference facility. On Tuesday, I received a phone call from the LCC telling us that our venue had been pulled, and that Mark Steyn would not be permitted to speak there. The reason offered by the LCC was that they had received pressure from local Islamic groups, and they didn’t want to alienate their Muslim clients. It’s interesting to note that the LCC is owned by the City of London, and is therefore a government operation.

I’m sure these Islamic groups are populated with moderate Muslims – just like the moderate Muslims who want to build a victory mosque at ground zero.
