Bureaucracy gone amok $$$.
Good, I figure that your the kind of person that can tough this out and see it through. As a professional Tradesman, I'd see you having a shop as your own to be a source of pride and accomplishment. Spending many happy hours doing what you have always enjoyed doing best.
My neighbor is a gutter install contractor and he says that to build a new house to sell at $1.4M CAD that the cost of Engineering, permits and inspections can total as high as $200k CAD. And that is for a new home in my hood.
The $8 Billion promised by our woke PM to build a million new homes over the next 10 years won't even cover the bureaucracy.
