In 2014, Canadians produced 961 kg per capita of non-hazardous waste, and spent about CAD$85 on waste management operating expenditure. Using aggregate data from Statistics Canada, multiple linear regression models were developed to examine diversion rates with respect to percentage of expenditure on various parameters related to waste management in Nova Scotia, Québec, Ontario, and nationally (in Canada). Budget allocation varies significantly in Nova Scotia with respect to time. On average, only 31% of the Nova Scotia’s budget was spent on collection and transportation, compared to the national average of 46%. Tipping fees were only significant in the national regression model, likely because some prairie provinces are using tipping fees to increase waste diversion. The Québec model was the least statistically significant. Negative regression coefficients were identified for the operation of recycling facilities in the Nova Scotia and Ontario models, however, they were less statistically significant, suggesting a more complex relationship. A lagged relationship between increases in budget allocation for operation of organics and recycling facilities and diversion rates was found in Québec, with a lag period of about 5–8 years. Overall, the Nova Scotia model had a much higher modelling adequacy, interesting considering its highest diversion rate in Canada.
