Apprenticeship and training

Every skilled tradesperson on Elmwood learned their trade somewhere, and for most of them it was through apprenticeship: years of paid work on site under the guidance of experienced workers, combined with blocks of technical training in a classroom and shop. Apprenticeship is how the construction industry reproduces its skills, and with large numbers of experienced workers retiring, it is also how the industry will survive. For a contractor, apprentices are a cost in their first years and an investment that pays back for decades. This lesson explains how apprenticeship works, what the rules require, how to plan apprentices into crews, and what makes apprentices finish.

How apprenticeship works in Canada

Apprenticeship in Canada is a provincial responsibility. In Ontario it is administered by Skilled Trades Ontario, which took over from the Ontario College of Trades in 2022 under the Building Opportunities in the Skilled Trades Act, 2021, together with the Ministry of Labour, Immigration, Training and Skills Development. An apprentice signs a registered training agreement with an employer sponsor, works under the supervision of certified journeypersons, records the skills they have learned in a logbook, attends levels of in-school training at a college or union training centre, and finally writes a certificate of qualification exam. Some trades are compulsory, meaning only certified workers or registered apprentices may perform the work: in construction these include electricians, plumbers, sheet metal workers and others. Others, including general carpentry, are voluntary in Ontario, although most union agreements and many employers expect certification.

The Red Seal Program sets interprovincial standards for about 55 trades, including carpenter, construction electrician, plumber, steamfitter-pipefitter, sheet metal worker and ironworker. A tradesperson who passes the Red Seal exam can work in that trade in any province or territory without retesting, which is valuable in a mobile industry.

Ratios and supervision

Apprentices must work under the supervision of certified journeypersons, and both the law and collective agreements limit how many apprentices may work per journeyperson. Ontario moved most trades with ratios to one apprentice for each journeyperson in 2018, and many collective agreements set their own ratios, sometimes stricter for first-year apprentices or for particular tasks. The point of a ratio is that each apprentice gets real supervision and teaching. A crew of eight apprentices and two journeypersons may be legal under some rules and still be a bad crew, because the apprentices will learn less and be at greater risk.

Luis builds apprentices into every crew deliberately. On Elmwood each forming crew of ten had three apprentices of different years and seven journeypersons, so that a first-year apprentice could learn from a fourth-year as well as from the journeypersons, and so that the crew still had the experience to work safely at the slab edge.

# Check apprentice ratios by crew against the agreement (illustrative rule: max 1 apprentice per journeyperson,
# and no more than 1 first-period apprentice per 3 journeypersons)
crews = {
    "Forming crew A": {"journeypersons": 7, "apprentices": [1, 2, 4]},
    "Forming crew B": {"journeypersons": 6, "apprentices": [1, 1, 3]},
    "Deck crew":      {"journeypersons": 4, "apprentices": [1, 1, 2, 3, 4]},
    "Finishing crew": {"journeypersons": 3, "apprentices": [2]},
}
for name, c in crews.items():
    j, a = c["journeypersons"], c["apprentices"]
    first = a.count(1)
    problems = []
    if len(a) > j:
        problems.append(f"{len(a)} apprentices for {j} journeypersons")
    if first > j // 3:
        problems.append(f"{first} first-period apprentices, max {j // 3}")
    print(f"{name:15s} J {j}  A {len(a)} (periods {a})  " + ("; ".join(problems) or "within ratio"))

Forming crew A  J 7  A 3 (periods [1, 2, 4])  within ratio
Forming crew B  J 6  A 3 (periods [1, 1, 3])  within ratio
Deck crew       J 4  A 5 (periods [1, 1, 2, 3, 4])  5 apprentices for 4 journeypersons; 2 first-period apprentices, max 1
Finishing crew  J 3  A 1 (periods [2])  within ratio

The deck crew has too many apprentices for its journeypersons and too many first-period apprentices. Luis moved one experienced carpenter from crew A and one first-period apprentice to the finishing crew, which brought every crew within the rules without changing the total workforce.

The business case for apprentices

Apprentices cost less per hour than journeypersons, but in their first months they also produce less and need more supervision. Over the course of an apprenticeship, the balance shifts: by the third and fourth periods, a good apprentice produces close to a journeyperson's output at a lower rate. Calder Ridge's estimators model this to set realistic crew productivity and to show project managers why apprentices are worth having.

# Apprentice cost and output relative to a journeyperson, by period (illustrative)
journey_wage = 48.50
periods = {
    # period: (wage as share of journey rate, output as share of journeyperson output, journeyperson time spent teaching per hour)
    1: (0.60, 0.40, 0.15),
    2: (0.70, 0.70, 0.08),
    3: (0.80, 0.88, 0.04),
    4: (0.90, 0.97, 0.01),
}
for p, (w, out, teach) in periods.items():
    cost = journey_wage * w + journey_wage * teach      # apprentice wage plus journeyperson teaching time
    cost_per_unit = cost / out
    print(f"period {p}: cost ${cost:5.2f}/h, output {out:.0%}, cost per unit of work ${cost_per_unit:5.2f} (journeyperson ${journey_wage:.2f})")

period 1: cost $36.38/h, output 40%, cost per unit of work $90.94 (journeyperson $48.50)
period 2: cost $37.83/h, output 70%, cost per unit of work $54.04 (journeyperson $48.50)
period 3: cost $40.74/h, output 88%, cost per unit of work $46.30 (journeyperson $48.50)
period 4: cost $44.13/h, output 97%, cost per unit of work $45.50 (journeyperson $48.50)

In this example, a first-period apprentice costs almost twice as much per unit of work as a journeyperson, a second-period apprentice about 11 percent more, and third- and fourth-period apprentices about 5 and 6 percent less. The numbers ignore benefits, which are often similar for apprentices and journeypersons, and the many intangible benefits: a pipeline of trained workers who know Calder Ridge's methods, loyalty, and the experienced workers' own learning from teaching. Contractors that hire apprentices only when targets or ratios force them to are paying the cost without collecting the return.

Why apprentices do not finish

Completion is the weak point of apprenticeship in Canada. According to the federal government, more than 100,000 new apprentices registered in 2024, but only about 34,000 completed their training that year. Studies of apprentices who leave point to several causes: interrupted work during downturns, financial strain during in-school training, poor supervision or mentoring, harassment or a hostile work environment, and difficulty with the in-school or exam requirements.

Aisha Rahman, the second-year apprentice on Elmwood, nearly quit in her first year. She was on a crew where she spent most days cleaning and moving material, and the foreman rarely explained anything. When Grace's month-one review uncovered it, Luis moved her to forming crew A, assigned a journeyperson mentor, and made sure her logbook started filling up. A year later she was leading the layout of embeds on one floor under her mentor's supervision, and she plans to write her certification exam on time.

Mentoring that works

A mentor is not the same as a supervisor. The foreman directs the apprentice's work each day; the mentor is an experienced tradesperson who takes responsibility for the apprentice's learning over months or years. Calder Ridge asks each mentor to do four things: show the apprentice how a task is done and explain why, then watch the apprentice do it and give specific feedback; check the logbook with the apprentice every month and plan which work processes come next; talk with the foreman so that the apprentice is assigned to the work they need; and be someone the apprentice can raise problems with, including problems with the crew.

Mentoring takes time, and time costs money on a fixed-price job. Calder Ridge recognizes it by giving mentors a short training course, counting mentoring as part of their job rather than an extra, and recognizing good mentors publicly at the annual safety and awards dinner. Luis also matches mentors and apprentices with care: a patient, articulate journeyperson is worth more as a mentor than the fastest carpenter on the floor.

Bringing new people into the trades

Many apprentices arrive through pre-apprenticeship programs: short courses, often run by colleges, union training centres, Indigenous organizations or community agencies, that teach basic safety, tools, trade math and site expectations and help participants find a sponsor. Calder Ridge takes several pre-apprenticeship graduates each year, and its experience is that they stay at higher rates than workers hired with no preparation, because they know what the work involves before they start. Secondary school programs such as the Ontario Youth Apprenticeship Program let students begin registered apprenticeship while still in school.

Government support for apprentices

Federal and provincial governments support apprenticeship with grants to apprentices, tax credits and grants to employers, and Employment Insurance during in-school training. In April 2026 the federal government announced Team Canada Strong, a $6 billion plan intended to recruit, train and hire 80,000 to 100,000 new Red Seal tradespeople over five years. It includes a weekly top-up of $400 during mandatory in-class training, a one-time $5,000 bonus on Red Seal certification, together worth up to $16,000 per apprentice in addition to Employment Insurance, an expanded apprenticeship service that can contribute up to $10,000 toward an apprentice's first-year wages, a digitized Red Seal program with online exams and logbooks, and a goal of halving the time it takes to become certified. Details of eligibility and delivery were still being rolled out in late 2026, so Grace checks the current rules before advising apprentices.

Training beyond apprenticeship

Training does not stop at certification. Journeypersons need training on new materials, equipment and methods; foremen need supervisory and leadership training; and everyone needs refresher safety training. Union training centres and trade associations offer much of this, and many contractors run their own programs. Calder Ridge's foreman development program covers planning a crew's week, running toolbox talks, the collective agreement, documentation, respectful supervision and coaching apprentices. It started the program after noticing that most of its foremen had been promoted because they were the best carpenters, not because anyone had taught them to lead.
