Income Taxes	11. Income Taxes The Company determines its estimated annual effective tax rate at the end of each interim period based on facts known at that time. The estimated annual effective tax rate is applied to the year-to-date pre-tax income at the end of each interim period.

The Company’s effective tax rate on income from continuing operations of 28.2% and 30.6% for the three and nine months ended September 26, 2014, respectively, differ from the Canadian statutory rate of 27.0% primarily due to the mix of income earned in jurisdictions with varying tax rates, losses in jurisdictions with a full valuation allowance, and the impact of discrete items for the period. The Company’s effective tax rate on income from continuing operations of 40.6% and 48.4% for the three and nine months ended September 27, 2013, respectively, differ from the Canadian statutory rate primarily due to the mix of income earned in jurisdictions with varying tax rates, losses in jurisdictions with a full valuation allowance, and the impact of discrete items for the period.
