I know that in Ontario York Region they have an Early Intervention program where they will test your child on communication and skills and see if there is anything 'off' as early as possible and then work with the family to get the child on track or get the help they need.

I am not sure where you are located though and what they offer. You might want to google Early intervention in your area or ask at the OEYC if they offer something like that in your area.
