Does the experience of Canadian tourist visa refusal have an impact?

Does the visa refusal experience in Canada have an impact? This problem must be of great concern to many people. Visa rejection will be recorded, and it will become more and more difficult to apply again. For those who have refused to sign, they can choose to go through the intermediary website. My brother was also refused a visa, and later it was handled through a website of "Reiteration Network". I heard that this website has something to do with the embassy, and the processing speed is very fast.
