With regard to NORAD operations, the Canadian Army is usually a supporting arm of the Canadian Armed Forces in NORAD activities. Perhaps a colleague from CJOC or potentially the commander of the Royal Canadian Air Force could contribute on that.
However, you did ask the question, sir, about training activities. Typically the Canadian Army participates in two of the four cyclical Nanook training exercises in the north. One is in the winter and one is in the summertime. Our most recent iterations of that were with approximately 100 soldiers from different parts of the country this year, as well as about two dozen local Rangers from Cambridge Bay and Resolute Bay.
