Update your calendars: The mid-May Los Angeles Screenings has prompted the CRTC to delay upcoming vertical integration hearings from May 9, 2011 to June 20, 2011.

The regulator said it was responding to a November 19 letter from CTV asking that the hearings be delayed to Fall 2011, or at least mid-June, because “each May, representatives from Canadian broadcast licensees travel to Hollywood to screen and purchase U.S. programming for the coming television season.”

The Canadians’ deal-making with studio suppliers is then followed up by Canadian advertiser pitches in early June.

Kevin Goldstein, vice president of regulatory affairs at CTVglobemedia, in the November 19 letter added that the annual Hollywood shopping expedition for broadcasters, and subsequent June Canadian Upfront presentations in Toronto, would leave top CTVglobemedia executives unable to participate in the May 9, 2011 hearing “in any material fashion.”

The CRTC, in its decision, pushed the new hearing date to June 20, in part to give top executives at BCE time to prepare for the vertical integration hearings, pending regulatory approval of their friendly takeover of CTV.

The regulator also delayed the deadline for submitting interventions by interested parties to April 27, 2011, from March 7, 2011.
