Google Doesn't Rank My Site for My Own Brand Name

I run a small business in Canada. Oddly, if you search my brand name, my own site doesn’t show up at all on the first page. Instead, Facebook, Instagram, and random sites that link to me outrank me.

I’ve submitted my sitemap to GSC, checked indexing, and built branded backlinks—but Google still ignores my homepage. It’s bad because people looking for me are funneled into other platforms where I lose control of the user journey.

Has anyone else experienced this? Is this Google punishing small/new sites, or do I need to approach brand SEO differently? At this point it feels like Google wants me to buy ads just to show up for my own name.
