Look, there is no certain trick or method in order to prove your home ties. Every one's case is different. Visa officer will take everyone's educational, financial and family background situation into consideration. He will do an overall assessment. If you are single, show your family members living in Pakistan. Don't show ,if your father is retired , it will give the impression that you want to work in Canada after studies. Don't show any relatives in Canada in any capacity. That's how you negate the impression of immigrant intent. Btw, nowadays, every student has a house and land in Pakistan it proves nothing.
