Yes, but I don't think Proof of Funds is a mandatory requirement like Express Entry. It is treated like a job offer for which you do not strictly speaking require proof of funds. However, it is required that you prove that you are able to establish yourself in Canada, and one way to prove that is that you have some settlement funds in your account. If you are going to reside in your employer's home, then that is also a proof, plus if your spouse has some education that can fetch him a job to support the family, that is another proof, plus the money in your account and the income that you will earn from your employment. All these are ways to prove you can establish yourself in Canada. If you have funds like the minimum required under Express Entry, great! If you don't have that much, but can prove these other factors I just mentioned, especially if you will be residing with your employer who is a family member, your case is also good, since you are more than likely to be assisted by that family member in getting established in Canada, with you spending less money. This is the result of my research.
