Quebec City hosts the Summit of the Americas Apr. 20-22, a meeting that will bring together the heads of state of Western Hemisphere countries. As has been the norm at such gatherings since the 1999 World Trade Organization meeting in Seattle was shut down by protesters, disruptions are expected. Local authorities estimate that as many as twenty thousand demonstrators will gather during the summit, and there is potential for disorder. A security zone has been established in Quebec City with entry barred Apr. 19-22 to anyone not participating in the conference. Common sense suggests deferring travel to Quebec City at this time, unless you plan to participate in either the meeting or the demonstrations against it. Other areas of Quebec province are not expected to be affected.
