Anyone know if insurance is mandatory for small business in Ontario?

My business is mainly online for the last 3 years and now I'm looking to open a show room, around 180 sq/ft only, with basically nothing valuable in it so don't say i'll regret if thieve breaks in LOL. There might be an office table and a chair, basically total value will be less than $500 I would say... that's why I don't care if I got break in haha...

yes, and for all businesses
