Overhead for Canadian Cancer Society runs about 50% (fundraising and admin costs), which is excessive.  They have two employees making more than 350k, and eight more making over 200k.  

Canadian Breast Cancer Foundation  (Run for the Cure) has an overhead percentage of 38% of funds raised, with 4 employees making over 200k.

Hopefully a merger will mean that overhead expenses can combine to an amount considerably lower than half the money raised, because right now this is  a deciding factor for many when choosing a charity.
