184 moving companies are federally registered in Ontario, California. Each listing below links to a full federal report: license status, real fleet size, and four years of consumer complaints by category.
A quote from a Ontario company means little until you know who is quoting: a carrier with trucks and crews in the area, or a sales office reselling your move. That distinction is the first line of every report, and it decides how your moving day actually goes. When comparing companies here, also check the wider California list: reputable carriers a town over often beat a risky mover next door.
