CIC doesn't compel us to take IELTS, CELPIP, TEF etc. They ONLY have a scoring system for Language abilities. One may choose to ignore it (at a RISK of scoring less for those points) if we think that we may still make it to the total [67] points or higher thru the other points criterion.
All the CIC wants is SOME proof. It might be by way of IELTS (or CELPIP), or TEF, or A 'Written Evidence'. However, the Written Evidence is NOT CONCLUSIVE. You are then at the mercy of the VO. Note CICs Own Words:

"If you believe that you can clearly demonstrate your level of proficiency through a written submission, follow the instructions in the table below... CIC strongly advises that you ONLY CHOOSE this option if your first language is English or French (READ MOTHER TONGUE)... Note: Test results will be used as *conclusive evidence of your language proficiency"...

*But, the 'written evidence' will not.
The bottomline is, if one thinks s/he can garner enough points thru the other 'selection criterions', he/she can ignore the Tests and can ONLY SUBMIT the 'Written Evidence'. The same is well detailed in the IMM-7000, Application Guide.
But generally speaking, it is always good to take the IELTS (or CELPIP) or TEF. U r then 'safer', rather than being on the 'mercy' of the VO's assimilation.
