Let's say CIC requires you to stay 10 year with your wife if not , you will lose your PR... I believe 1000 % you WILL NOT DIVORCE your wife... When you are dating with your wife , you and your wife must have so many plans , from plan A to Z.....That's why your wife is sure to married you and sponsoring you.....
Your wife has a job , that's why she can sponsor you....You also have a job....Now you are afraid have a baby because of financial situation ? Do you think is it like your country or other countries which needs a lot of money for having a baby for first day of pregnancy?
How much money do you need to pay hospital, doctor , school , food etc?
If you live in other country which must pay a lot of money to study in school ( the best schools tuitions are in US Dollar even the country's currency is not in US dollar and the country is third world country which salary is so low ,cost of living is so high and unemployment rate is so high ). So I can understand your situation.....
You are not Family man and please don't use other members statement like " You don't know my situations , bla bla.....
I believe your first priority is only To secure your PR , send money to your parent , invite them , to show people in your country ," Hey , I am Canadian PR now.....I am a Tax Payer .....!!!!!
Do you think your wife is dumb and can't calculate the cost of having a baby ? She loves you and that's why she wants a baby from you !!!!
