Abstract: Colorectal cancer is the third most diagnosed cancer and second leading cause of cancer related deaths in Canada. As Ontario has the largest population in Canada, it also has great disparities in colorectal cancer incidence. The region of Timiskaming has the highest incidence for colorectal cancer, while the region of Peel has the lowest incidence for colorectal cancer in Ontario. The purpose of this study is to identify the dominant non-nutritional modifiable environmental risk factors in the region of Timiskaming compared to the region of Peel that may be associated with diverging colorectal cancer incidence rates. The three objectives of the study included performing a systematic review on available published literature, creating an assessment questionnaire tool regarding environmental exposures, and utilizing the questionnaire assessment tool within a pilot study group while expanding it into the communities of interest. Findings indicate that there are dominant non-nutritional modifiable environmental risk factors in the regions of Timiskaming and Peel that may be associated with colorectal cancer. The dominant factors identified are tobacco/smoking, alcohol use, pesticides/organochlorines, and metal toxins. Following this study, it is imperative that recommendations are directed at a community level and relate to the assessment of potential non-nutritional modifiable environmental risk factors. Future research should accompany a larger sample size, multiple participant communities, and catering of the questionnaire tool towards the communities of interest.
