Skilled Trades Ontario expands on-site certification exams to training delivery agents
Skilled Trades Ontario (STO) has announced that it will expand on-site certification exam delivery to all Training Delivery Agents (TDAs) that offer a final level of in-class apprenticeship training.
“This expansion marks another important milestone in our work to modernize and improve Ontario’s apprenticeship system,” said CEO Candice White. “By bringing exams directly to where apprentices train, we’re removing barriers, reducing wait times, and helping more skilled trades professionals get certified and into the workforce faster.”
The expansion builds on a pilot launched under the Ministry of Labour, Immigration, Training and Skills Development, which began with 31 TDA locations across the province. Since assuming responsibility for exam administration on April 2, 2025, Skilled Trades Ontario has broadened on-site delivery to 54 TDA locations.
STO says the change will help reduce travel for apprentices writing exams, shorten wait times to write, and support faster entry to the workforce for employers who are hiring now.
As of today, the program is being made permanent and will be available to all TDAs who are authorized to provide final level training— over 100 locations across Ontario — ensuring that eligible apprentices can write their final certification exams directly at their training location.
“Skilled trades workers are essential to building Ontario’s future. We’re helping apprentices reach certification faster and with fewer barriers,” said Labour Minister David Piccini. “This investment gives apprentices more flexibility to get the training they need and delivers more certified workers ready to take on the jobs that keep our economy growing.”
