Takiong some of the courses that you think would be the most beneficial to you in your home daycare and then when you do interview you can say "have taken some ECE courses" and while you dont' have a full ECE degree it will still show your committment to learning more about providing quality care.
There is a course available at some colleges that is specific to home daycare - St. Lawarence College in Kingston used to offer it here in Ontario - not sure if they still do. And I think it was availble through distance learning too.
Another course that is available and specific to home daycare is available through the Ottawa CCPRN in actual hands on workshops but you can also do it by distance through some groups - there was a childcare association in Barrie that was offering the program online - it is in three sections and several modules in each.
Anything that shows you are taking an interest in the children and providing better care will be important to parents.
