Trying to complete 2017 tax return ,butdoesn't "appear" that car expenses are allowed ,even tho' car needed for work?

If your employer signs a T2200 Declaration for employment expenses, stating that once you arrive at work you are required to use your vehicle to do work related travel , you would then keep a log book and enter under employment expenses.  If you are not required to use your vehicle once you arrive at work there is no claim for to and from work, it is a personal expense.
