British Expats - What Documents Do My Kids Need

Hi everyone and sorry if this has been asked 1000 times.

Me and my wife are planning to travel to Barrie,ON. We are both UK residents currently and she will be the main applicant on a student visa with me attached for a work visa. We are trying to clarify what the one year old and eight year old kids will need in the way of travel docs. Am I correct in thinking that they will not need anything like eTA or visas (student or visitor) as they are listed on the family forms my wife will submit with her student visa? The course she will be studying is 2 years. If you need more info, feel free to ask. I just don't want to get there to be told the kids don't have the right travel docs and be sent home. TY in advance
