Murphy's is represented by Molson in Canada, and I guess they got tired of trying to do battle with Guinness, as it's not available in very many places at all.
They had it on tap at Prohibition (Queen near Broadview) when I was there a year or so ago, so that might be worth a shot. And it can sometimes be found at Irish pubs, although that can be hit and miss.
