Is their a place for us not at retirement age with husband receiving disability retirement but not social security while I work full time?

Can you afford to pay for any home care services?T here is homecare sevices in Ottawa that serves individuals who require assistance to live independently in the comfort of their own homes. But please be sure that you take time to think things through before you make any decisions. Best wishes to you!

Do you perhaps mean checking in on him to make sure he has not had another seizure and injured himself? Even then someone can't be there all the time. Would it help to check by phone while you are ast work and if he does not answer have someone you can call to go and check on him.
In our area there is quite long wait for senior housing so if you go this route be prepared for that. You said you work for the Salvation Army do they have any programs you may qualify for?

When you say checked in on, I'm not sure what they would check. He should be seeing a Neurologist at least every 3 months, with bloodwork to determine that seizure meds are at proper levels and electrolytes are in balance. Checking his vital signs, as visiting nurses do, won't help.

If he is 55 yrs. you are qualified for most senior residences including moving into a retirement community. I live in the largest and biggest one in Sun City, AZ and someone must be 55 to live here. But, if you are not, it only requires one to be 55. So wherever you live, check into senior apartments or retirement apartments. Good luck!

SS may have denied just because the seizures weren't frequent enough in their opinion to preclude working. I do know a couple of people who are working, with their seizures medically/surgically controlled. They have relatives who stay with them, if needed.
I do have suggestions, 1) hire someone to sit with him after a hospitalization for a few days, 2) get him signed up with a health alert system like Lifeline, or 3) move into a senior housing community or assisted living facility with him. Most senior residential apartments are available if even only one spouse is 55 or over. Most have intercoms and/or people who volunteer for daily well-checks and community dining so someone would be able to help him or notify you. Personally, I would go with #1 and #2 to see how it works out.
