You can try it with the old IELTS or by presenting documents for your English knowledge but then you are leaving your case up to the visa officer to basically award you as many or few points as they feel like.
Generally IELTS and other such tests and considered valid for 2 years after they are taken. CIC says: "Your test results must not be more than one year old at the time that you submit your application." ( see http://www.cic.gc.ca/english/information/applications/guides/EG72.asp )
CIC does not recommend you use documents to support your English knowledge unless English is your first language. People have had different experience with documents. Some people have been awarded no points with documents and some have been awarded some but less than they asked for. Very few people manage to get full points with documents unless English is their first language.
It's still up to you if you want to try it but if you need the English points to make 67, you risk losing your application and having to apply again.
