Thank you for the question.
First, a general word of support for apprenticeship programs. They're terrific ways to enter the labour force and build lifetime income.
My broader concern would be around the terms of the programs, whether they are portable from jurisdiction to jurisdiction. In other words, is a requirement for crane operator A in Quebec transportable to Ontario in similar employment? Are the journeymen-to-apprenticeship ratios reasonable? Are the number of hours reasonable? Plenty of them have numbers around 2,000 to 3,000. Depending on what it is, that sounds just fine.
Armine mentioned 9,000 hours. I don't know which ones would have 9,000 hours, but I know they do exist; 9,000 hours would allow you to just about complete a residency in neurosurgery, so you have to wonder about that.
