Want to sponsor my wife in singapore??

Hi, I'm a Canadian ESL teacher teaching in Singapore. I now have my employment visa and I am eligible to sponsor my wife. My wife has no education, due to her family's financial situation. Since I am making enough money to support her without her needing to work, can she still immigrate to Singapore? My wife is from Malaysia. On the form it asks for education, and she doesn't have it. Will that be a problem? If i'm sponsoring her as my spouse and I'll be supporting her and she won't be working anyway,so would that be a problem?
