WHEN CALLS THE HEART: Aaron Douglas to guest star

When I was on vacation in Vancouver in September, Aaron filmed a guest starring role in episode of a tv series and I was lucky enough to tag along. I wasn’t allowed to watch him film (I had to stay in the trailer) but while everyone was on a lunch break Aaron took me for a walk around set. Can anyone guess what the show is from the photos? And you can’t cheat because I haven’t added it to his IMDB page yet ?

EDIT: Julie guessed correctly. Aaron is going to be on an episode of WHEN CALLS THE HEART. He will be in episode 6×11. I will post a reminder once it gets closer to the airdate. According to Wikipedia the shows airs on the Hallmark Channel in the United States and on Super Channel and CBC in Canada. And internationally on Netflix.
