Forsythe, who earned the nickname Mr. B.C. for his extensive knowledge of the province, first joined CBC Radio in 1984 as a host in Prince Rupert. He later moved to Kelowna, and then to Vancouver to host The Afternoon Show in 1991.
In 1996 he became the host of B.C. Almanac, CBC Radio One's provincewide noon show. The popular show has earned a place in listeners' hearts with its popular call-ins and frequent road trips to host broadcasts from all corners of the province.
Forsythe announced earlier this year that after 30 years with CBC, he planned to retire after the annual Christmas Card of the Air show on Dec. 24.
Listeners are invited to send their greetings to family and friends across B.C. between noon and 1 p.m. PT by calling toll free to 1-800-825-5950, or in the Lower Mainland to 604-669-3733, or *690 on cellphones.
