Thanks for the welcome! Next time I am in Moncton I will have to take a look!
Work has taken me to Victoria and I checked out Comic Strip (3 comic book shops within in a 30 second walk) on Johnson Street and I didn't come up with a Chaos War... but did find a signed copy of Alpha Flight #128, No Future Part 1 of 3, now I need to find parts 2 and 3.
