Reeb was promoted to the Global network's top news job in June, 2008 after returning to the Toronto head office in September, 2006. Previously, he served as an on-air correspondent, most notably as Global TV's bureau chief in Washington, DC and as a political reporter in the network's Ottawa bureau. 
Prior to joining the national news, Reeb was a political reporter and commentator for Global Ontario CIII, where among other responsibilities he hosted Focus Ontario. Previous to that, he worked 10 years in radio, with approximately half that time spent in smaller cities such as Saskatoon and Yellowknife, and the other half covering national and international events for Broadcast News, the radio service of the Canadian Press.
In addition to serving as a backup anchor on Global National, other network programs Reeb hosted for Global included Global Sunday, and the short-lived Ottawa Inside-Out. In his executive role, Reeb in 2008 championed the launch of a new current affairs program on Global entitled "16x9 - The Bigger Picture." 
Following Shaw's purchase of Global and other broadcast assets of the former Canwest in 2010, Reeb announced Shaw would be undertaking an aggressive expansion of Global News both on television and online, with the addition of local morning newscasts in six markets across Canada. He later announced the addition of a national morning show, a national political talk show, The West Block and Shaw's first regional all-news channel Global News: BC 1. 
The son of a United Church of Canada minister, Reeb spent his early childhood in Ontario, before the family settled in Westlock, Alberta when Reeb was 13. He got his start in broadcast journalism at age 16 at CFOK (AM), a Westlock radio station. He graduated from Lethbridge College in 1988 and helps fund an annual scholarship in his name at the institution where he was named Distinguished Alumni of the Year in 2003.  He is a recipient of the Alberta Centennial Medal and the Provincial Awards Celebrating Excellence.
