I don't remember seeing this on the CIC site or anything but the wiki page says
Foreign government authorities may require the production of a PR Card in some circumstances:
Canadian permanent residents require a PR Card, unless the person's passport in itself is sufficient for exemption. A Canadian PR Card holder, in general may travel visa-free to the following countries: Aruba, the Bahamas, Bermuda, Cayman Islands, Costa Rica,the Dominican Republic, El Salvador, Honduras, Jamaica, Mexico, Nicaragua, South Korea and the Turks & Caicos Islands.
So, my wife with just a PR card can travel visa-free to these places?
