James Corey Glass, apprentice mortician and United States Army deserter, was keeping an unusually close eye on the text messages coming into his cellphone. He was hoping to hear that a court had blocked the Canadian government’s attempt to send him back to the United States. On Wednesday afternoon, the message came: Mr. Glass, 25, could remain in Canada while he appealed his removal order by the country’s Immigration Department. It was a welcome reprieve, he said, but well short of a guarantee that he and other deserters could make Canada their new home. The Canadian government’s effort to remove Mr. Glass contrasts with the warm reception given to deserters and draft avoiders from the United States during the war in Vietnam. And although the war in Iraq has very little support among Canadians, the situation of Mr. Glass and others who abandoned their military positions provokes a wide range of responses. For American soldiers seeking an escape, Canada is no longer a guaranteed haven.
