insurance requirements for independant haulers

im having problem obtaining insurance, im 49 been driving for over 5 yrs long haul very clean cvor (no tickets/accidents), did all required paper work, broker came back and wanted reference letters from previous employers (understandable), submitted the ones i could get (missing one, they where very upset i left and wouldnt give one), Broker came back said she needs insurance names and policy numbers from previous employers (WTF), now i have two that dont want to give info ?????????
My problem is that if this a requirement there must be a legal recourse for me to get this info from them.
CAN SOMEBODY PLEASE HELP OR STEER IN RIGHT DIRECTION

 

yes im in canada, going to move over boarder, and we wonder why the the trucking industry suffering

 

AMEN
