Canadian abdominal compression brands?

An abdominal back brace helps my lightheadedness and even my heart rate but it’s a back brace so it’s bulky and not really comfy to wear. I ordered a sleeve type on Amazon but it didn’t helped and it has really annoying wires in it. I just want the fabric nothing bulky or restrictive when bending. I see Jelliebend is recommended often but I’m in Canada and it’s too expensive for me. Are there any similar brands in Canada anyone can recommend? I only want the stomach compression sleeve not any leggings, shorts or anything else. Any recommendation would be appreciated
