Episode #4.3 - S4-E3
Character mistake: On the website of the Saint Marie Heritage Society, there's an ample mention of Catherine's bar where the society gathers.

Episode #4.4 - S4-E4
Character mistake: Close captions in the episode write down the Frenglish mish-mash by Goodman as "leoffer" without space, when he's saying "le offer" ("offer" in French is "offre", but he's just making a joke, with "le" making automatically everything sound French).
Episode #4.7 - S4-E7
Character mistake: Annette Burgess calls herself an "Inspirational entrepreneuress." That word just does not exist. It's 'female entrepreneur", or "entrepreneuse." (00:11:55)
Episode #4.7 - S4-E7
