Expectant parents run into issues because they do things like get medical notes saying they need parents to come provide support/help during pregnancy and after the child is born. Unless there is a medically complex pregnancy then no medical note is needed and may create more problems. For example if woman is in and out of the hospital then a medical note would be warranted and parents visiting for medical reasons would be reasonable to provide emotional support. Applicants also mention things like helping around the house and help caring for the baby in their application. This can be interpreted as working illegally and creates concerns this may be a longterm arrangement especially if parents ask to visit for many months. The language used is really important. Wanting to visit Canada to meet their new grandchild and visit their child and their child’s spouse is a very normal reason for a visit. If it is a relatively short visit with proof of approved leave and jobs to return plus any other ties to their home country then there is a high chance of supervisa approval if child/their spouse meets LICO and they have savings.
