A key factor behind Toronto’s growing reputation as a business capital is its attractiveness to start-up companies. Ranked among the top 18 start-up ecosystems in the world, Toronto has a rich talent pool. Beyond these considerations, it is Toronto’s business environment, access to resources, and business costs that make it such an appealing place to launch start-ups, especially a duct cleaning business. This has called a great choice of duct cleaners but also has increased the chances of receiving sub-par service. Toronto is also known as the king of telemarketing scams for air duct cleaning. Looking blindly in Toronto for duct cleaning company can be a costly mistake.
