There are no wage requirements however your application can certainly be refused if your wage is too low and not aligned to the NOC under which you are claiming work experience.
Low is actually $15 in Ontario (not $14) for your NOC. Which city are you in? That may help you (or maybe not).

Being paid only minimum wage and below the "low" for your NOC puts you at risk of refusal since IRCC may doubt you actually carried out these job accountabilities based on your pay.
