## Is tool and die maker a compulsory trade in Ontario?

No. Tool and Die Maker is a prescribed trade under section 1 of O. Reg. 876/21, but it is not on the compulsory list in section 2. That means you can legally work in this trade in Ontario without holding a Certificate of Qualification. Certification is voluntary and serves as formal proof of competency to employers and clients.

Voluntary classification only covers certification under the Building Opportunities in the Skilled Trades Act. Specific work within the trade can still require separate licences or permits under other Ontario statutes, so confirm the rules for the actual work being done. The 23 trades where certification is mandatory are on the [compulsory trades list](https://ontariocertificationregistry.ca/trades/compulsory/).

## 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.
