In Toronto, there are about 40000 deaths in car crashes every year. With an average amount of driving within 50 years, chances of dying in a car roughly 1 in 100. In addition, SUVs are more dangerous for their occupants, since there are more SUVs on the road, expect the chances of dying in a car crash to increase over the next few years. So the chances of being in a car accident are one-chance-in-6, 700 that a person could be in a car accident (Evans et al, 2009). And for cancer, statistic shows that 38.08% of women or one-change-in-3 that a woman will more likely to develop a cancer, and for man, 44.85% of men or one-change-in-2 that a man will more likely to develop a cancer (Rosen et al, 2011)         

            With comparing the chances of illness caused by tap water and chances of cancer and car accident, is quite far. In Toronto, Tap water is safe enough to be drunk without additional filtration. Toronto's Medical Officer of Health and the Ministry of the Environment test tap water regularly. The water is tested continuously after treatment and drinking water samples is taken every four to six hours to confirm the absence of bacteria. For the treatment, necessary chemical is used to treat the water, including chlorine to kill E.coli and other bacteria that may be present (City of Toronto, 2012)       

            In conclusion, we shouldn’t spend more money from tax dollars on water treatment in Canada. Beside the fact that tap water in Canada is drinkable, the fact is also proven one of the city in Canada has won international tap water competition (CBC news, 2012). So our tax dollars should be spend for our main concerned, such as cancer trial, unemployment, Health Care, illegal drugs, homelessness, immigrants and etc. With knowing the facts that tap water is safe enough, we can reduce use of water bottle. Therefore, we can save our environment.
