Fire tv Stick HD

Tried the fire stick 4k but doesn't work because its a in house operating system what I found out , can't side load so bought the new fire stick hd wifi 6 , thought what I've read I get Telus TV Plus but I was wrong again because Telus doesn't show up on app store , I get City TV , Bell fibre optic but no Telus . Can someone help or is there another stick other then Amazon I can get for my older tv
