No. CIC's strict requirement is the following (52 weeks * 30hrs per week) = 1,560 hrs. There are no exceptions to this requirement.
Note: the EE system only allows applicants to enter the work Start and End dates in the format 'mm/yyyy'. Hence the system awards points to applicants at the start of the '12 month' regardless of when during the 1st month the applicant started working (Eg a person who started working on 15 January will receive CRS points for working 1 year in December. If an ITA is accepted and the person applies the VO has the authority to deny the application if the CRS points given to the applicant for 1 yr of work enabled them to accumulate CRS points to exceed the CRS requirement for the round in which they received the ITA (Eg if a person had CRS points of 460, and the CRS score in the draw in which they received the ITA was 450, the VO will re-calculate the score by subtracting '40 CRS points' for 1 year of Canadian work experience and send the applicant a rejection notice.
Sorry for the long post.
