However, while you are on visitor status, you will not have health care in BC and neither will your children so you should think about having accident/emergency insurance in case something happens.
Actually, in BC you (and your children) can get health care
before landing (i.e., while you are still technically a visitor). The wait time (balance of the month + 2 months) can start when CIC accepts the PR application or when the fees were paid. See the following threads for details. It should save you a few months of travel insurance premiums.
