In October 2013 there were only 1800 continuances according to Industry Canada from the old CCA to the new CNCA.  That number has now jumped to  4175 corporations by May 31, 2014 and is probably higher over the last 5 weeks.   That being said there are about 19,000 Federal corporations and many clearly need to continue or face dissolution after October 17, 2014.  For registered charities dissolution will also eventually result in loss of registered charity status.
