Not too sure if it's too late or not, but as a fellow Canadian, I too have had issues
with pillows not standing up.  I was getting a lot of headaches and my neck/back was always killing me.  Sitting at a desk hunched over all day doesn’t help.  At one point I even bought a “MyPillow”.  Useless. 
I started reading some pillow comments on Amazon and came across this:
https://www.amazon.ca/Memory-Foam-Pillow-Oreiller-King-Queen/dp/B07PYRL8QM/ref=sr_1_1?keywords=EnerPlex&qid=1669835725&qu=eyJxc2MiOiIzLjYxIiwicXNhIjoiMi40OSIsInFzcCI6IjEuOTAifQ%3D%3D&rnid=5264023011&s=kitchen&sr=1-1&th=1

What I like is that you can adjust the firmness. My wife and I each got one. She kept hers full, I ended up taking out some of the stuffing. The first couple of days the smell of the pillows was a little much, but still fine. After about 3 days, WHAM. They were amazing. We got these in July so more than 4 months ago. Headaches are waaaay down. Sleeping comfort is waaaay up. We're giving some to our kids for Christmas. Not cheap, but not pricey, considering you'd pay anything for a great sleep.
Anyhow, my 2 cents worth.
