From the Corner Gas Wikipedia Page

Production of an animated adaptation was announced in December 2016. Slated to debut on The Comedy Network on April 2, 2018, Corner Gas Animated will feature all of the original cast voicing their original characters, except for Janet Wright who died in 2016. The role of Emma will instead be voiced by actress Corrine Koslo.

Jesus Christ, they couldn't just write her character out of the show? They must have really hated her.
