Interested in finding examples of Canadian municipalities which have
worked successfully with the news media. Examples of good public
information offices.

Not sure if this is exactly what you are looking for- but on CP24- a
news channel in Toronto they air two shows "The Mayor" and "The Chief"
see discriptions below :

"The Mayor"

Each month, CP24 gives the people who call Toronto home a chance to
speak directly with their Mayor. Mayor David Miller joins "CityPulse"
Anchor Anne Mroczkowski, for a LIVE "one on one" with the residents of
our city, on the issues that matter most to Torontonians. No middle
man, no special interest groups - just your chance to voice your
opinions and concerns to our Mayor.

"The Chief"

Each month, CP24 gives viewers a chance to go one-on-one with Toronto
Police Chief Julian Fantino. Host Gord Martineau joins the Chief LIVE
in our newsroom as Torontonians call, fax and email their crime
concerns.
