The federal government provides a list of clinics where volunteers offer free services during the tax season to those with modest income (please see the maximums in the link on the right under the eligibility section). It is important to get your tax filing done every year, even if your income is low, so that you get all the financial benefits you are eligible for and may not know about.
Also, in BC, there is TaxAid that provides free tax assistance to people with disabilities whose income is less than $35,000 per year:Â https://taxaiddabc.org/
