Depends where the applicant is coming from. The applicant is expected to pay things from cost of airfare, supervisa insurance, clothing, accomodation, to food.
Since the children or grandchildren are based in Canada, they should know how much those things costs in Canada. Btw, how much funds do they have in the bank account?
If I add money in bank account of applicant since I'll be covering 2400k plus 1k flight cost will it be possible to show sudden funds I have maintained around 7k balance for 2 months before that 4 month balance of 2?5k
