I have income but my wife does not have income....when I file, how come it seems like turbo tax is just producing one return to CRA?

You are correct you should be filing a coupled return, and there should be 2 tax returns to file at the end if it has been done correctly. 

Not sure what may or may not have occurred but I will ask you to follow directives provided below for assistance on adding your spouse to your tax return:

Hope this helps.
