Probus and PROBUS are both in widespread use and there seems little appetite for enforcing one over the other. The version using title case (Probus) can be found in publications from the United Kingdom, its original home. The all-caps version (PROBUS) appeals to many who see it as an acronym.

As such, it is in the hands of our independently operated clubs to decide how they prefer to write the name of our wonderful organization.

However, our federally registered non-profit organization is to be written as PROBUS Canada.
