This is a liberal government problem. They say there are budget constraints but in actual fact they have no concept of value for dollars. 
They could hire a small number of speech pathologists which are at a higher rate of pay to do assessments and then they should bring in CDA's to do the one on one work. They know how to develope treatment plans according to the assessment. They could hire more of them at a lesser pay rate and treat more children. These are fully trained accredited professionals that seem to be underutilized because our government keeps insisting on using Chefs instead of Sous Chefs. 
This government is poorly run when it come to health services and delivering value for our tax dollars. 
I fear what is going to happen when the population ages and more people have strokes and need treatment that they just can't or won't provide.
