So wouldn't GWB give Steven Harper permission to visit Cuba and Venezuela.?

Why did Canada's Steven Harper ignore Cuba and Venezuela on his recent summer vacation in the Carribean region...here we have two of the more successful countries, not open for debate in this question, and he wanders among the losers of the region...did he call George and George would not allow him to...I am serious...in reality the buffoon probably thought he was going to visit pirates.
