Please know that you are not legally obligated to do anything for her. She might be your wife but she can't force you to submit the application. You are here and she is there, there is nothing she can do. If you have prepared the papers to apply for her PR throw them in the garbage.
If you were married in India, I advise that you get on the phone with an indian lawyer. Keep any proof you have that she only married you to gain entry into Canada. The lawyer will advise if there is a way to annul the marriage or how to start the divorce proceedings. It is very important to keep all proof that she frauded you. Once your lawyer contacts her for divorce she may turn the other leaf again, pretend that she loves you and has no clue of what he is talking about with fraud marriages.
If she is harassing your parents advise them to take matters to the police. Get a restraining order if it becomes unbearable.
If you don't know any lawyer in India, I suggest you seek out the New Delhi thread and ask if anyone knows a reputable lawyer in the area which you are from. I am sure they will gladly help you.
The others are right, you can apply to bring your parents here on a supervisa. you may want to look into that on the CIC website and consider it as an option. Also, she is wrong you dont have any obligation to give her money unless you sponsor her. You have not sponsored her yet so you don't have to worry about this.
