I am not a legal expert but to be on the safe side I would wait until she actually has her visa approved. If there are no problems the Visa can be approved fairly quickly, I have had clients that experienced delays due to additional testing requirements. This is due to things like epidemics in certain regions and the need to safeguard Canadian citizens. This is one of the responsibilities of Citizenship and Immigration Canada to protect the health and welfare of Canadians, just so you know our tax dollars are not going to waste.
Keep in mind when Citizenship and Immigration grants a super visa it is based on the documents submitted at time of application, I would not do anything at this type that could cause problems with her Visa.
I will share one of the major problems with Super Visa Travel Insurance I have experienced, people buy Insurance get the Visa approved then cancel the policy and try to enter Canada with a cancelled insurance certificate or don't bother renewing insurance while in Canada for an additional year.
First this is immigration fraud and more importantly it is a complete disregard for the welfare of ones parents and/or grandparents.
Thanks so much Gary! Your help is much appreciated. I will take your advise. God Bless
