Have you seen any insects on the leaves? The damage could be caused by a few different things and it could be challenging to figure it out without more information. One thing to look for, are the larvae of the Raspberry Sawfly. They are green, might be hard to see, and they feed on the underside of the leaves. Here is a website with more information about them: http://www.omafra.gov.on.ca/english/crops/pub360/notes/raspsawfly.htm
