When I started this blog in 2003, there weren't many of them to read. That said, we encouraged one another through uncharted waters. Blogs have changed a lot since those early collegial days.
The grandfather of labour (labor) and employment law blogs is Jottings by an Employer's Lawyer by Mike Fox. Mike recently wrote a post entitled The Evolution of Employment Law in which he discussed the emergence of dependent contractors as a classification of employee in the U.S.. He refers to What if There Were a New Type of Worker? Dependent Contractor.
We've been dealing with this classification (or intermediate category as it is sometimes called in the case law) for some time. It is a middle ground between independent contractor on the one hand and employee on the other.
One of the earliest cases is Carter v. Bell & Sons (Canada) Ltd., 1936 CanLII 75 (ON CA). There are lots of cases, though, in different contexts. Another leading case is McKee v. Reid's Heritage Homes Ltd., 2009 ONCA 916 (CanLII). Economic dependency is essential in the analysis. An important recent case is McCormick v. Fasken Martineau DuMoulin LLP, 2014 SCC 39 (CanLII).
There are some important differences between the employment laws in Canada and the US, though I wasn't aware of this being one of them.
