Hi @xgillianx ,
Hopefully the information in this article can help you!

To highlight from the article, the amount for an eligible dependant credit on line 30400 is often referred to by its former name “Equivalent to Spouse.” Most commonly associated with single-parent families, this non-refundable tax credit doesn’t just apply to children. One of the larger credits, the eligible dependant amount can go up to approximately $15,705 (or more if your dependant qualifies for the Canada caregiver amount).
Thank you 🙂
