It will not affect the hearing. Canada's economy does not rely on refugees to improve it, nor does it get affected if refugees don't work.
However, if you find a job you will fill your time with something useful. If you don't work, you will spend most of your time thinking about your refugee claim, you will add more to your stress. It is much better if you find a job. I hope you will. If you don't find a job, try to do some volunteer work. Keep yourself busy, not only thinking about the refugee claim. The wait time is forever. Doing nothing in the meantime will not be good for your mental wellbeing.
In addition, even if you get social assistance, for sure it will not be enough to cover all of your expenses.
Look for a job and start immediately. Good luck man.
