Furthermore, by deciding that online broadcasts from traditional broadcasters, such as radio and TV stations, will be exempt from CRTC control, the agency has addressed a particular concern of the committee which wanted the government to clarify the distinction, if any, between telecommunications and broadcasting.
The agency addressed a letter to the committee for the government to clarify the distinction if any between telecommunications and broadcasting. 
The committee addressed a concern, they didn't address a letter. The statement hints that an idea was addressed, not a physical thing such as a letter.
