Andrea Horwath looks like she is promising to support a $12 minimum wage June 2016. If inflation were to exist at 3% per year, Ms. Horwath's proposal would actually be slightly less than the Liberal proposal to index to inflation which would be about $12.20.
Nonsense. Both plans begin with $11 per hour by June 1 of this year. Assuming 3% (which is unlikely), for the Libs under your scenario I calculate it would be $11.33 the next year, and then the year after (2016) it would be $11.67, not $12.20. So even under your extremely high CPI, the Liberal plan would be less than the NDP plan. 3% of $11.00 is 33 cents, which is less than the 50 cents the NDP is proposing for two years. 50 cents is about 4.55% of $11. So, the CPI would have to be greater than 4.55% for the next two years for the Liberal plan to be superior to the NDP plan. This is practically impossible. The NDP plan is superior.
The CPI for next two years is forecast at 2%, so under the Liberal plan, the minimum wage in June 2015 would be $11.22, and then in June 2016 would be $11.44. Under the NDP plan, the minimum wage in June 2015 would be $11.50, and in June 2016 would be $12.00. Thus, the NDP plan is 56 cents higher in 2016 than the Liberal plan.
