To open business or not?

A viable solution to the annual tax problem has been used by many people in Canada, but is it causing a higher tax rate for the rest of the population? It has been known that if you open up a home business, such as selling candles or other merchandise from a home-based office, you can file for 50% of the majority of living expenses as deductions. These deductions include natural gas, rent, internet, cable and even gas and car expenses. This has been pulling me in to the option of opening up my own home business... but if so many people are doing this, the Canadian government is getting less and less money each year and solves their financial problem by increasing the percentage that they may take off of each cheque of non-home business earnings. For the mean time I may as well jump on the bandwagon and profit, while keeping my eyes open for alternative ways in which the government may take money from consumers... hey, I hear that in Ontario their liquor stores are government owned, versus the privately owned liquor stores in Alberta! A little bird told me.
