I have 3 dependant children. I was able to deduct childcare as an expense but do we also get a deduction for dependant child? Thanks

What you can claim for a dependant child if you are a single parent you can add one of your children as an eligible dependent. You need to add them as your dependents in order to get your Canada Child Benefit.

If you have a child who has a disability then you will be able to also claim Disability Tax Credit.
