The article's phrasing is rather confusing and seems to indicate there are two separate proposed images. In reality, there is a single proposed image, that being the World War I Vimy Memorial in France, dedicated to Canadian troops that fought in the war. Does the memorial have statues of nude women? Yes. Can you see it clearly in the proposed image for the $20 note? Not from what I can tell.
For reference, what the "Woman" (Representing peace) is holding is a torch. While I'm not Canadian, it's a bit more upsetting that people are mistaking a memorial to those whom have given their lives in the line of duty as being "pornographic".
