I live in Toronto,Canada.My ex boss took 1500 cad from me in cash.He returned the same by paying me a personal check 1500 cad.Since i quit the job against his will,he is threating to sue me showing that he had paid me 1500 cad as a loan which i have not returned.In both cases when i paid him or he paid me there is no witness or cosigner.please advice as to what he can do trying to herm me.what action i should take as a precautionery measure?
