If they removed Box Mountain, and whatever crap is under it, Chantal and Peetz could easily fit some wire restaurant shelving in that space. Honestly, I'm surprised they didn't do that from the very beginning, because that shelving is cheap and holds a ton of shit, and their kitchen doesn't have much storage (and certainly not for bulky appliances).
Normal, sane people would have done that. But as we've seen over and over again, there is nothing normal or sane about Chantal or James.
If Chantal got nothing else out of the Covid-19 lockdowns, she learned to take food delivery completely for granted, and make it her new default.
So if she lived in Toronto, it would mean not only more regular restaurants to order from, but also more fast food, including chains that aren't in her area. She'd still live in a filthy hovel, and not go anywhere, but she'd have a whole new world of food delivery options. And that's the only thing that matters to her.
There was clearly no benefit for either her mom or grandma, but Chantal got to get out of her hovel overnight and enjoy the relative luxury of her uncle's house as if it was her own. And who knows what was on the menu for dinner--but at least there weren't any pesky leftovers, thanks to Chantal! And she no doubt got to stop for fast food both coming and going. That counts for something, doesn't it?
I feel bad for her mom, but honestly, if she expected Chantal to provide any kind of practical help or emotional support, she really ought to have known better by now.
Are "funeral potatoes" a thing in Canada, as they are in the Upper Midwest, and among Mormons? Because a mukbang of funeral potatoes (with mounds of shredded cheese), while telling stories of stuff she ate in childhood, would be Chantal's most fitting way to memorialize Grandma.
