Canada had two elements earmarked for the northern flank of NATO: A battle group from 2 CMBG in Petawawa with the Allied Command Europe (ACE) Mobile Force (a collection of several battle groups from different NATO countries) which was primarily air transportable and the Combined Air-Sea Transportable (CAST) Brigade Group (primarily the bulk of 5 CMBG in Valcartier) which was to be transported to Norway on RORO ships provided by the Norwegians. There were also two fighter squadrons and some other odds and sods.
CAST only exercised twice--once in Canada and once on Ex Brave Lion in 1986. The exercise was generally not successful. The concept died a quick death during a major defense review the following year.
We never stored any equipment of any significance in Norway for either force that I know of as it was all needed back in Canada for day-to-day training anyway.
