Can a baby be baptized in a Catholic Church if the mother does not have papers proving she was baptized? I tried to baptize my baby at a local Catholic Church in Toronto, but the priest told me I need to provide documents proving I was baptized.  I don't have such documents because I was baptized and confirmed in another country, and I don't even remember in which church.  Without the paperwork from my country of birth the priest refuses to baptize my son.  Is this really a requirement in the catholic church?  Or is it possible to find another priest who is more easy going?
In order for a child to be baptized, there must be "a founded hope that the infant will be brought up in the Catholic religion" (Code of Canon Law, Canon 868 section 1). That is, the priest must judge it reasonable to believe that you will raise your child Catholic. This is reasonable from the church's point of view since it baptizes infants so that, growing in grace in the Church, they will be saved.

Is it necessary for you, then, to prove that you are baptized? Canon law has no such requirement. In fact, it's perfectly possible for the child of a non-Catholic to be baptized. (The complete requirements for valid, licit baptism of an infant are listed in Canon 868 of the Code of Canon Law). What's important is for the priest to feel comfortable with the idea that you'll raise your child Catholic. This is usually not a problem, especially if you have been a member of your parish for some time.
