Canada is the one place I have had bad experiences with MR's.
One time I was going to YVR for the days. Immigragtion did not like my reason (that I wanted to take advantage of a cheap fare). They pulled me aside. Asked question after question. Went through my backpack. All they found was my notebook, in which was a family tree of names. I was preparing a Eulogy for a congregant who had died. Must have looked like a drug chain to them!
After about an hour they let me go.
