There is a new entrance off the parking lot near Queen Street. Archivist Glenn Lockwood has consolidated everything from the former vault, now demolished, into the main shelving so space is at a premium. Retrievals may take a bit longer. For the next two years researchers should note that the Archives will not be accessible to the physically challenged, nor will there be access to washrooms. Consider delaying your visit for a few weeks unless your need is urgent.
The archives website is at www.ottawa.anglican.ca/Archives.html
Thanks to Brian Glenn for conveying this information.
