Gas, Home and car insurance in my tax return expence?

I'm a self employed programmer, I work in my home (don't have office)
my question is can I consider my home rent or car insurance-gas as my job expences in tax return forms?
I'm useing my car to see some of my customers (not always).

Yes, you can, for the reasonable share of expenses relating to earn self employed income.

The Income Tax Act limits the circumstances under which a self-employed individual can deduct the costs related to a workspace in the home. They are confined to situations where the space is used exclusively to earn income from a business and on a regular and continuous basis for meeting clients, customers or patients, or if it is the individual鈥檚 principal place of business.

This claim may be based on the proportionate space within the home that is used as a workplace. Eligible expenses include rent, mortgage interest, realty taxes, insurance, utilities and maintenance. It is generally not advisable to claim capital cost allowance, on a portion of the home because that portion would not qualify for the principal residence exemption when it is ultimately sold.

For the car, you may claim around 50 cents per km for trips to see a client, that covers insurance, gas and depreciation.
