Part of the reason the CPP disability appeal system is under stress is that according to the fall 2015 Auditor General's report, there has been an increase in demand on the program. In paragraph 6.6 on page 1, the audit finds that in the 2000-01 fiscal year, the CPP disability program had 282,000 beneficiaries, who together received just over $2.5 billion in disability benefits. By the 2013-14 fiscal year, the program had almost 330,000 beneficiaries, an increase of 17%, who received just over $4 billion in disability benefits, or an increase of 50%.
What share of the increase in beneficiaries from 282,000 to 330,000 can be attributed to demographic causes alone?
