There is a very practical solution. The super visa is not mandatory. People can apply to come to Canada with temporary status for a limited time.
Who says they have to apply to come to Canada for 12 months or two years? They can choose to come for a few weeks, a month or two months. The most important thing is that an operational guideline is needed: If the parent or grandparent applies for two to three months and the officer is not satisfied, the family must be allowed to amend the application or apply for a super visa. They should start with a standard application for a short visit, a short stay in Canada, and then they can amend the application if the officer requires that they apply for a super visa.
