new to business, what type of certification needed Options

[toolman]

Hi guys.
I currently run a carpet, tile and grout cleaning business and want to add power washing as another service.
i currently clean a restaurant on a monthly basis and the manager offered me to clean the hoods.
the problem is i have never done it and he knows that but is still willing to let me do them to gain some experience.

the main question is are there any certifications needed in ontario and if i rent the equipment what should i look for.

thanks
