@ rontarrant:
If the OP is actually talking about Computer Music magazine, you should be able to find it at a Chapters, or other place with a comprehensive magazine rack in Ottawa. I live in Cornwall, so there is NO chance of finding something exotic like that here, but I bought a Computer Music magazine at Presse Internationale in Montreal yesterday, and I remember being able to find them at the Chapters in Pointe Claire (Montreal's West Island). Expect to pay premium import prices of around 20 dollars plus of course tax.
