I do my taxes online through turbo tax and the statement of business activities is part of the program. If you do the paper method, it should also be in the package, it has been so long since i used paper returns that I cant remember if it is there or not. For rent/utilities you can only claim a portion based on the square footage you use for daycare. All of the info you need is on the Canada Revenue agency website, they have a section called Using your home for daycare.
