The Canadian actor played Young Barry over eight episodes starting with The Flash's first season. He also recurred on When Calls the Heart, playing the son of Chelah Horsdal’s Cat Montgomery. A Tri City News story said he died "suddenly" on Thursday but didn't list a cause of death. The Flash star Grant Gustin mourned Williams' death on Instagram, writing: "My thoughts and prayers will be with him and his family during what is I’m sure an unimaginably difficult time for them. Please keep Logan and his family in your thoughts and prayers during what has been a strange and trying time for us all. Sending love to everyone."
