Unfortunately, you do not meet the minimum language ability for English. You must have Canadian Language Benchmark level 7 or higher. For IELTS, in the Writing category, that corresponds to a score of 6 or higher.
Federal Skilled Worker Program
You must meet the minimum level of Canadian Language Benchmark (CLB) 7
in English or Niveaux de compétence linguistique canadiens (NCLC) 7 in
French for your first official language in all four [emphasis
mine] language abilities.
The actual equivalency scores are here. Scroll down and click the Federal Skilled Worker Program entry. The minimum score in each category/band is 6.0. The overall score is not used. You must take the General IELTS test, not the Academic one. This page also states that you cannot use an averaged score unless you have a disability and could not complete one of the sections.
The required scores for the Skilled Trades program are less--CLB 5 for speaking and listening and CLB 4 for writing and reading. That equates to IELTS scores of 5.0 or greater for CLB 5 and 3.5 for reading and 4.0 for writing.
There's a third category, Canadian Experience Class. The language requirement depends upon the National Occupational Classification (NOC) of the job.
NOC 0 or A job, the minimum level is CLB 7 (English) or NCLC 7 (French).
NOC B job, the minimum level is CLB 5 (English) or NCLC 5 (French).
