Do I call myself an RD when presenting at a
conference in another province? 

The laws and regulations about using the dietitian title are different from province to province, so the answer to this question will depend on where you are presenting. In some provinces, it would be sufficient to tell the audience that you are a dietitian registered in the province of Ontario. This makes it clear that you are not registered with the regulatory body in the province where you are presenting.

In other provinces, however, you must be registered with the regulatory body there in order to identify yourself as a dietitian. These provinces typically have a “courtesy” or shortterm registration status for which you can apply. It is best to contact the regulatory body well in advance of your conference or presentation to ensure you have time to make any necessary arrangements.
