Tourist visa application for children whose parents already have a visa

[josefranciscopl]

I am from the Dominican Republic. My wife and I have tourist visas, and we want to apply for visas for our children. I would like to know if I need to fill out the representative form since I will be completing the applications. Also, since our children will be traveling with us, what should I answer for the question: "Is your family member currently, or will they be, living in Canada with a parent or legal guardian for their entire stay?"
