Mr. Speaker, in 2011 national historic sites under the administration of Parks Canada were generally open from the Victoria Day weekend to the Thanksgiving weekend. In 2012 Parks Canada is aligning and reducing the duration of operating seasons and hours in national historic sites to match peak visitation periods and to minimize off-season requirements. The majority of national historic sites have maintained similar opening and closing dates for 2012; however, some sites opened on June 1 and will close on the Labour Day weekend.
In the House of Commons on September 17th, 2012. See this statement in context.
