Hi, we request you to try this:
While showing the quick panel, Click options (3 dot button) and then tap on button order.
You may see mobile hotspot on the top, just drag it down and place it to the location you want the button to show.
What device do you have?
Are you talking about the WiFi QS Tile or Mobile HotSpot Toggle?
If you don't see the WiFi QS Tile, which would be pretty strange, Click on the 3 Dot Menu Top Right & Edit Buttons & See if it needs to dragged down to the active QS Tiles.
I'm pretty sure that if it's not there, you can add the HotSpot Toggle using adb.
None of the Canadian Carriers prevent you from using it.
There was a time when the Mobile Data Toggle wasn't available, and for the longest time, Samsung was blaming the Carriers, but finally admitted that it was Samsung that didn't include the Data Toggle.
It's easy enough to add using adb.
You need to download & install Samsung's USB drivers to your computer & Platform-Tools.
Open up PowerShell on your computer & run the adb command I posted
settings put secure sysui_qs_tiles "$(settings get secure sysui_qs_tiles),Hotspot"
