denied for a visit visa

[abc]

hi all...i was denied for a tourist visa three times already for the reason that they were not convinced for me to leave canada if given the opportunity . is previous denials and  pending immigrant application have an impact if i will try to apply again? btw im single, 30 y/o f, Filipino citizen but currently residing in ksa, well travelled,  have assets to show and  have sisters in canada . is there anything i can do to prove them that my intention is purely tourism? need ur help guys....
