I know that everyone's situation is different. And I am not against parent sponsorship, I believe if they have no support system (other family, friends) in their country of origin than it is clearly the best decision to have them with the family they have here in Canada.
Just because we won't sponsor parents to Canada does not mean that we don't appreciate for what they have done for us.
I am just being honest, and wanted honest opinions, everyone has their right to an opinion and to make decisions for their family that suit them best.
As an example, if I sponsor parents here, will I really be taking care of them? Will I leave my career to stay home and take care of elderly parents? What if they need 24/7 medical assistance as in a RN, this is not cheap, it is not free.
A friend of mine, an unmarried, professional, mid 40s, held a good position in a national company, had to leave work to take care of her mom because she could not find anyone competent or anyone who she could trust to take care of her mom who needed 24/7 assistance, money was not an issue, she paid plenty to several agencies who sent incompetent caretakers. So she left her work, took care of her mom for almost 2 years to when her mom passed away. With 2 years away from her professional career, had a hard time getting decent employment, went through most of her savings, and in the end took a lesser position just to start working again.
For us, we didn't really have to make that decision, when we talked to my husbands parents about possibly sponsoring them here in the future, they said "absolutely not", especially since my husband's sisters live near them, and all other family, they instead gave us a building lot to build a house there. God willing, we will get super visa for them, so they can visit when they want, and can stay as long as they want or need. But they are really too settled in their home, their city and their country.
