From the official website, http://www.esdc.gc.ca/eng/jobs/foreign_workers/higher_skilled/general/index.shtml link that is called "requirements", is quoted below:
Cap on Low-wage category Positions
offering a wage to a TFW Employers that is below the provincial/territorial median hourly wage will be subject to a maximum 10% cap on the proportion of low-wage TFWs. The cap will be phased in over the next 2 years to provide employers who use the Program with time to transition to a Canadian workforce.
Employers that have a low-wage TFW workforce will be:
limited to 30% or frozen at their current level, whichever is lower;
reduced to 20% beginning July 1, 2015; and
further reduced to 10% on July 1, 2016.
The 10% cap is the maximum percentage of low-wage TFWs that an employer will be allowed to have at a work site, as of July 2016.
As of now, there are 2 contradicting pieces of info around that, from their site.
From my understanding, the high-low skilled distinction remains as is, but on top of each of them, they added the low wage (below median) and high wage (above median). The difference is that you have to check the wage offered across the provincial median, not the occupation median.
So, Ontario has $21, your's is $22.5, you are high-skilled (1226), high-wage (since the wage offered is above provincial median), Transition plan has to be submitted as well.

Part of it:
There is now a concept of “high-wage” versus “low-wage” occupations.
This is determined by comparing the wage being offered to the TFW to the provincial/territorial median wage. If the wage being offered for the position is above the provincial/territorial median wage, it will be considered a high-wage position. If it is not, then it is a low-wage position.
The applicable provincial/territorial median wages are set out in the LMIA application form, and are also available at this link: Provincial Median Wages. This provincial median wage figure needs to be compared to the wage being offered to the TFW for the position.
Whether an occupation is “high-wage” or “low-wage” will dictate the path an employer must follow to transition to a Canadian workforce.
If the employer is applying for a high-wage occupation, the employer must provide a Transition Plan in most situations. A Transition Plan is not required when applying for an LMIA for a low-wage occupation.
