One government program that I feel has not been very well promoted is the disability tax credit. As a result, there's a whole industry of consultants who, for quite hefty fees, will help people apply for the credit. New Democratic MPs have been holding public information sessions across the country to try to get the word out to people that they can apply for this benefit directly without going through consultants.
I wonder if the presence of private consultants promoting what should be public services might be an indication of where more public advertising is warranted.
