From Western Catholic Reporter:
A statement issued July 16 by Joseph Zwilling, New York archdiocesan communications director, was apparently the first official indication that such a visit would take place in the spring.
Zwilling told Catholic News Service July 16 that unnamed sources said the pope would visit in the spring instead of late September, when the new session of the UN General Assembly opens, because of next year's presidential elections. It would be Pope Benedict's first visit to the United Nations and his first visit as pope to the United States...
...The pope is also expected to come to Canada for the International Eucharistic Congress next June 15-22 in Quebec City.
