[Facts] Blame Bruce Lansky for this misconcepted meaning...

And also, I feel it fits better on Name Facts rather than Name Opinions, but anyway...
I cannot find any kanji writing that even remotely has a meaning of "mirror" AND has the readings to, shi or toshi. 鏡, which means "mirror," have the Sino-JP readings kyō + kei and the native reading kagami (+ the nanori/name readings aki + kaga(n)). Jisho does have a word for a mirror image, 鏡像, but it is read as kyōzō.
For more on where the name Toshi stems from, see my post on Toshirō here: https://beyondsakuraandhiroshi.wordpress.com/2020/04/19/toshiro/
