Tanner was born in Mankota, about 500 kilometres southwest of Yorkton. He began his journalism journey when he attended the Western Academy Broadcasting College for radio broadcasting and journalism in Saskatoon.
After graduation, he moved to Swift Current, where he spent the next two and a half years working as the weekend news reporter, the morning news reporter for the online news site, and host of an afternoon show on the local radio station.
From there, Tanner moved to Williams Lake, where he spent six months and then another six-month stint at Yorkon This Week working as a news reporter once again.
Tanner then landed at 620 CKRM in Regina, where we would spend the next two and a half years. After a short hiatus, Tanner rejoined Harvard Media at GX94
