CTV National News is CTV's flagship newscast, which airs at 11:00 pm local time on the CTV stations across Canada. It also airs on CTV News Channel, CTV's 24-hour cable news television channel, live at 10:00 pm Eastern—or 11:00 Atlantic, when the newscast begins its nightly run across the network—with hourly repeats until 2:00 am Eastern. The previous day's newscast can be seen on the Internet. The anchors are Lisa LaFlamme on weekdays, and Sandie Rinaldo on weekends. The program is also broadcast in High-Definition. LaFlamme succeeded longtime weekday anchor Lloyd Robertson during the second half of 2011, following Robertson's retirement. Substitute anchors include Rinaldo, Kevin Newman, Beverly Thomson, Ken Shaw, Dan Matheson, Scott Laurie, Marci Ien, Todd van der Heyden, Marcia MacMillan, Jon Erlichman and Omar Sachedina. The title CTV National News was rarely used in the 1990s and early 2000s; weeknights, the program was called CTV News with Lloyd Robertson and on the weekends, CTV News with Sandie Rinaldo.
