    I don't know the requirements in Canada.

    That said, typically you need at least one more circuit. there should be a 20 amp receptacle at the sink/vanity, and it should be GFI protected

    You have a light over the shower. There are real limits on that. A recessed light with a glass lens specifically for a wet location (shower) is an easy and inexpensive solution, and will light it up well. But the lens must be completely rated for fitting in a shower.

    Anything else would demand that the light be protected by a GFI, which could either be a receptacle or a breaker in a panel.

    I am getting ready to install a fan/light in a shower stall for a customer, and all such equipment, being open, must be protected by a GFI. I am replacing an outdated sub panel right across the hall, so I'll just drop a GFI breaker in that and dedicate it to the fan/light.

    Understand that strictly speaking, you cannot hang anything on the GFI that is for the vanity. If you do and the inspector spots it, he will most likely make you redo the whole mess. The circuit for the vanity needs to be beefy enough to run a hair dryer, you see.

    What I do not see in your drawing, which is miserably hard to read, is an indication of where your panel is.

    Current code would also require that you have all the outlets in the basement be GFI, except the pump, and the outlet for that should be a single plug, not a duplex plug, indicating that it is a sole function circuit. At least, here it would be.

    Not that we have basements and sump pumps down here.

    So you should certainly expect to add a circuit, and possibly two. I assume non-metalic cable is permitted there. It is cheap and easy to work with.

    The previous post is a bit incorrect. You are required to have a dedicated circuit for the bathroom. The receptacles and shower light require GFCI protection, so feeding the bath from a GFCI breaker would be a good idea. Alternatively, the loads could be fed through a GFCI receptacle. Doing this is more convenient if when the GFCI needs to be reset.

    Receptacles in the unfinished basement or in the bath need to have GFCI protection. If you are finishing other rooms in the basement, they must have AFCI protection.

    Not necessarily. One circuit serving only the recpts. can go to more than one bathroom
    No. Only the recepts. Sometimes the instructions for a light call for GFCI protection but the NEC doesn't.
    True.
    They require AFCI's in Canada? Pitty them as well.

    Even if they are not bedrooms?
