From a media release:

As announced last night on The Shopping Channel (TSC), beloved personality Richard Nester will retire as host on December 16, 2016, following 21 years of delighting customers across the country with his charismatic quick-wit and infectious energy. Host Sean Keane will take over Nester’s hours on TSC.

A Niagara, ON native, Nester moved to Toronto 36 years ago, where he worked behind-the-scenes at TVO before making his on-screen debut at TSC. Since joining the company in 1995, Nester has relished the opportunity to work in the fast-paced, dynamic environment of live TV, introducing customers across the country to the latest and greatest TSC products. He counts getting to know the late Joan Rivers, meeting viewers from all over Canada, and working with big names like George Foreman, Suzanne Somers, and Richard Simmons as career highlights.
