Spouse’s work permits are not guaranteed if you are approved. Your study permit may be approved because your tie to return is your spouse. Strong reasons to return are family. So you need to show strong ties to return if you both want to come (jobs, income properties, business, investments etc.). If you are taking a Masters/Phd then spouse has a better chance of approval. For funds, you need to show $26k in living expenses so you are using all your savings to come to Canada. You will want to show how the program will give you more financial benefits/higher pay to justify the costs.
