Since the filter thread is 43mm have you tried searching for a 43mm lens hood? If Canon does not offer one you could try looking at sites such as B&H Photo or Amazon or the online photo/video retailer of your choice.

Any 43mm filter should work and a UV filter is a good one to have. I would make sure the lens hood will allow you to attach a filter. A polarizing filter and neutral density filters also come in handy.
