    How old is old? If they are Canon auto focus EF lenses, then yes. If they are Canon manual focus FD or FL lenses, then no.

    The fact that they're Canon doesn't really matter nowadays, what matters is whether or not they are autofocus EF type lenses.

    If not, you can forget it.

    If they are EF type autofocus lenses you're ok.

    Canon changed their lens mount, making all their manual focus lenses totally incompatible with their modern cameras. Even the adapters cannot achieve infinity focus with them unless you get one with additional lens elements in it, which degrades the image quality severely.

    You may have heard that older manual focus SLR lenses can be used on new DSLRs. This is true if the brand is Nikon or Pentax. Canon changed their lens mount when they moved from manual to auto focus. Only the newer autofocus lenses will work on the DSLR. These are easy to identify because they have electronic contacts on the lens mount. The older ones were purly mechanical.

    There is/was an adapter available to convert the older FD mount to the EF mount but they are not worth the trouble IMHO.

    I haven't seen an adapter in a while. Canon came out with the EF lenses in 1986(?), so they are probably rare today.
