Does these documents and funds are sufficient to make the Visa Application? or Can I include anymore support documents to make my application more stronger? Please advise me ASAP.
No, these are not strong applications. Here's why:
1. Your travel to Sweden was for business/company work, right? Similarly, for your UK visit. In other words, you do not have previous travel history to prove to the visa officer that you will return to India. I'm assuming your dad and wife don't have any travel history as well.
2. You have not established that your parents are dependent on you. Your sisters don't count as family ties if they are married or live in other cities.
3. Your dad, wife and child have not proved that they have reasons to return to India.
4. Your dad's land cannot be a reason for you to return to India because you don't own that property.
5. If you need to borrow CAD 7.500 as a travel loan, it indicates a weak financial situation + it would make the visa officer suspect the reasons for your visit.
Not sure what you mean by 'savings in hand'?
PF cannot be shown as funds for your visit.
6. Don't book flight tickets nor pay for hotels. These don't guarantee visas.
In short, IMO, your application fails to prove:
1. Why would you want to visit Canada as a first-time traveler + why with your entire family (except your mom)?
2. Why would you spend significant money on a visit when you don't have any compelling reason to visit Canada (Read: No relatives or immediate family)?
