So I have mixed feelings on that. On the one hand, there's all the red tape, with commensurate cost increases, and possibly unnecessary babysitting. On the other hand, we have installers (and DIYers) who spec and usually install systems in a most shocking way, and hopefully this, if implemented correctly, will solve 90% of those issues. It all depends on the implementation, the legislation and regulations are useless without it.
So I can understand why, and it's not the WC government's fault, they are just responding to what they see as a very dangerous situation. To avoid it, the industry needs to do more to regulate itself. There have been brave attempts, like those of SAPVIA, but we are a lawless country, so no consequences. Our society isn't mature enough yet to demand and enforce good practices, so we get bullied by the government instead.
