The ex-McLaren man was given a five-place grid penalty for his part in the crash that saw both cars end up in the barriers at turn one in Montreal.
Stewards will meet again in Austria this weekend after Force India claimed to have evidence that clears their driver, but Massa is in no doubt about where responsibility lies.
He told reporters: "I was very disappointed with him in the hospital [after the crash]. I said that it was dangerous and that he needs to learn, but he just turned and left.
"When somebody is paying so many penalties, is causing so many problems, you cannot believe him. I will not trust him anymore, definitely.
"When I will be behind him, I will think three times where I need to go because I don't know what he's going to do. I hope he learns. Otherwise he will pay more penalties in the future."
Perez responded: "We believe we have enough evidence to prove that I did nothing wrong. He has his opinion, I have my opinion. We just have to sit down."
Massa is currently two points behind Perez in the drivers' standings.
