It is the same if you as a home owner, hire a roofer or some other contractor to perform work at your residence. It is in your best interest to ensure that their employees are covered by WSIB. If not, you do expose yourself (or your insurers) to possible litigation if someone gets injured on your property.
If there are any freight brokers who have not registered for this meeting, you are missing out on some very important information. WSIB tried a few years ago to classify our industry in the same group as carriers. Fortunately, after months of intensive lobbying, the NTBA was able to get them to reconsider and it resulted in the rate we pay today. There are strong indications that they are trying to increase our rate again, during their "re-evaluation" process for all industries in Ontario. If we as an association, can speak with one voice, we can possibly get them to reconsider. Chances of that happening after they implement a change are slim and extremely difficult to do. I can't speak for the other brokers in Ontario, but I do not want to pay 10 times more in WSIB coverage for my employees.
