Hello,  
 I suffer from  Complex regional pain syndrome (CRPS) is a chronic, severe pain condition that usually affects an arm or a leg, typically developing after an injury, surgery, stroke, or heart attack  and Fibromyalgia..   I am already on CPPD and PWD  for my disabilities.    
I heard ,   I heard it's very DIFFICULT to be approved by the government for Disability Tax Credit and Canada Disability Benefit.  
I have "invisible " conditions...    But  unable to work at all.     If I can get approved it would help me greatly monthly for my small income. 
Thank you for any guidance.     

Unfortunately, we don't practice Disability Tax Credit (DTC) law here. To find a lawyer with that specialization, I would suggest contacting your provincial law society's referral service. That said, step 1 to getting approved would be to speak to your doctor about the application forms, and making sure that they are willing to support you.

If you have an LTD insurance questions for us, please just let me know.

Lastly, you can also read about certain other provincial and federal government assistance programs that may be available to you on our website, at: https://stlawyers.ca/disability-law/faq/government-income-support-programs/ (not an exhaustive list).
