We've heard similar rumours, but I don't have evidence to that effect. Certainly with respect to those Canadian citizens who were resident in the camp, the Government of Canada had offered consular assistance to them over an extended period of time. The first time they chose to take advantage of that was in June, and there did not seem to be any problem with their decision to leave the camp at that time.
On December 13th, 2011. See this statement in context.
