1985 - Robertson Davies, What's Bred in the Bone; Morley Callaghan, Our Lady of the Snows; Loverboy, Lovin' Every Minute of It; Rush, Power Windows
1986 - Triumph, The Sport of Kings
through mid-year 1987 - Bryan Adams, Into the Fire; Michael Ignatieff, The Russian Album; M. T. Kelly, A Dream Like Mine
Other tid-bits - Tom Cochrane and Red Ryder played in Thunder Bay at the Fort Williams Gardens in August of that year (http://www.tomcochrane.info/pasttour/pasttour_1987.php). There were probably rumors in late 1987 about Motorhead coming to Thunder Bay in February of '88. I'm sure the new Rush album due in September of 1987, Hold Your Fire, was being discussed.
