Can stepfathers reunite and immigrate to Canada?

Yes, but there are some necessary conditions. First, your stepfather has the conditions and ability to vouch for you, and he is willing to vouch for you! (because he needs to give the federal government a promise of 10), and whether you are covered, such as your age, whether you are still a student who depends on your parents (full-time), your physical condition, your physical condition, whether you have had bad behavior, your biological father's consent statement, etc. . . .
