All materials (text and music) will be provided in print. Registration will be available on line. Due to printing constraints, registrants after July 15 may not be able to have a full printed copy of the program.
Delegates can take advantage of the many dining options available in the immediate area of St. George’s. Delegates are welcome to dine together for the final banquet (a la carte).
St. Georges Church is fully accessible. Parking is available on the neighbourhood streets.
