Employment Expenses

I received my T2200 form from my employer and work from home 60 percent of the time.  It indicates supplies are covered by the employer.  I get provided with paper, pens, pencils etc.

 

Maintenance and repairs.  However, I don't get covered for the following and wondering if these are claimable under Maintenance and Repairs for the home:

 

1.  Batteries for fire alarm

2.  Cleaning products for home: cleaning gloves, paper towels

3.  Lawn care products

4.  Products to clean my wall unit air conditioner: requires special cleaner, protective sheets, etc.

5.  Tools to maintain home:  ladder, screwdriver set

6.  Ergonomic supports for my chair (hard to get this covered through employer)
