Hudak has made job creation the centrepiece of his election platform, promising a PC government would bring a million jobs to Ontario over eight years, although about half of those would be created through normal economic growth.
Hudak was forced to defend his numbers in Niagara Falls today when he was repeatedly asked if his party had misinterpreted information from a Conference Board of Canada report, which the Liberals have alleged resulted in the PCs vastly overinflating their job estimates.
Certain economists have also recently penned columns questioning the Tory math, focusing in particular on the possibility that the PCs confused the term "person years of employment" with permanent jobs.
But Hudak insisted his party's calculations, which he said were based on a "mountain of evidence," were sound.
Party officials later told reporters that they had used some data sources that dealt in person years of employment along with others that measured employment in different ways to come up with the jobs figures in their platform.
