I had the same reason given for my refusal recently. I have had over 50 visits to Canada over 20 years, studied there 3 years and graduated from a Canadian college and have held multiple-entry TRVs pretty much continuously for the last 15 years. My most recent TRV expired a few months ago and the application for a new one was denied due to "Travel History". Maybe they think I've spend enough money in Canada already?
