Voluntary classification only covers certification under the Building Opportunities in the Skilled Trades Act.

Yes. Cement (Concrete) Finisher is one of the 33 trades that section 4 of O. Reg. 876/21 makes subject to an apprentice to journeyperson ratio.

## Already experienced? The Trade Equivalency Assessment

Workers with experience from outside Ontario's apprenticeship system, or from another country, can apply for a Trade Equivalency Assessment instead of starting an apprenticeship. Approval requires verifiable evidence of competency in the trade's Training Standard and experience at least equal to the trade's total training time; if approved, you challenge the certifying exam directly. The assessment costs $235 plus HST, and a reassessment with new evidence costs $100 plus HST, per [Skilled Trades Ontario's Trade Equivalency Assessment page](https://www.skilledtradesontario.ca/experienced-workers/trade-equivalency-assessment/).

## Certification is not the only paperwork

A Certificate of Qualification covers the person. Running a business in the trade carries its own obligations: many Ontario municipalities require a contractor licence on top of personal certification, and construction employers must complete WSIB registration before work begins. Both are indexed on our sister site: [municipal contractor licensing requirements by city](https://ontariotraderegistry.ca/licensing/) and [WSIB Form 1000, registration of constructors and employers](https://ontariotraderegistry.ca/compliance/wsib-form-1000/), on Ontario Trade Registry.
