There is a question on the online form where an applicant is asked if he has been ever denied a visa? Did you answer yes to it? If you applied for a visitors visa which was denied, you should have answered yes to this question. Answering yes does not impact your application in any way. An application for a tourist visa is for a temporary entry, but since the immigration perceived that you may not leave Canada, your visa was denied. However, when you file an application for the PR, you state your intention to permanently move to Canada, and if you meet the requirements, you will be granted the visa.
If you stated no to the question, knowingly that your tourist visa was denied, it would amount to misrepresentation. At this stage you should send a CSE and let CIC know of the rejection.
