Hi!
What views are you talking about? There's cic.gc.ca official website with all the rules and criteria described.
Yes, you can apply for PR and immigrate without your family members. Howerver, you must include them in your applications as dependents and then either mark "Accompanying" or "Not accompanying" in the application forms. This is a must and it affects the minimum amount of settlement funds you will have to demonstrate in the very beginning, as well as at a later stage whenever required. If you fail to include your dependents to your PR application this will result either in rejection (due to misrepresentation of facts) or in impossibility of further sponsorship of your family members in the future.
