Recoding was not carried out.
All the datasets of Canada have a problematic mix of levels.
It is unclear whether the code 6 corresponding to post-secondary certificate 
belongs to medium or high (ISCED 4C/5B).
According to the Canadian country expert it is more likely that most post-secondary
diplomas should indeed be classified as high education.
This results in an unlikely high percentage of high education.
As 23% of the persons are concerned, the mix of education levels 
has a notable effect on the results.

If LIS users want to pursue a recode they may do so on their own responsability.
The mapping below may serve as suggestion. 
The problematic category is pointed out.
