How Do You Go From Supply Teaching to a Permanent Position in Canada?
In most Canadian provinces, supply or occasional teaching is not just a fallback while you wait for something better — it is the primary pathway into permanent employment. School boards in Ontario, BC, and Alberta overwhelmingly hire permanent teachers from within their existing occasional teacher pool. Understanding how this system works, and how to use it strategically, is the difference between a slow and fast path to a permanent contract.
Why Occasional Teaching Is the Path In
The logic from a board's perspective is straightforward: when a permanent position opens, they prefer to hire someone whose teaching they've already observed, who has built relationships with staff, and whose reliability is known. An occasional teacher who has been in their schools for a year or two has all of those advantages over an outside applicant on paper.
In Ontario, the Elementary Teachers' Federation of Ontario (ETFO) and the Ontario Secondary School Teachers' Federation (OSSTF) confirm that the substantial majority of permanent hires at most boards come from the occasional teacher list. The same pattern holds in BC and Alberta.
Step 1: Get on Multiple Occasional Teacher Lists
There is no rule preventing you from being on the occasional teacher list at more than one board. In Ontario, it is common for new teachers to register with three to five boards simultaneously. Getting on the list is the first goal — it is generally less competitive than permanent hiring.
What boards look for when adding to the occasional list:
- Valid provincial teaching certificate
- Criminal record check (Vulnerable Sector Check)
- Two or three references, ideally from teacher education supervisors or principals who have observed you teach
- Willingness to travel within the board's geography
Apply early. Ontario boards often open their occasional teacher list applications in the spring (March–May) for September availability. Missing this window can mean waiting another year.
Step 2: Be Available and Reliable
The most important thing you can do as an occasional teacher is accept assignments consistently. Boards track your call acceptance rate — teachers who routinely decline calls move down the informal priority list that dispatchers use when calling out assignments.
Practical tips:
- Accept any assignment early in your time on the list, even if it's not your preferred grade or subject — exposure matters more than specialisation at this stage
- Arrive early, leave plans for the next supply teacher if you know you'll be returning, and send a brief summary to the classroom teacher
- Introduce yourself to the principal every time you're in a new school — they are often the ones who request specific supply teachers for long-term assignments
Step 3: Land a Long-Term Occasional (LTO) Assignment
A long-term occasional (LTO) assignment is a supply contract covering a regular teacher's extended leave — typically a parental leave, medical leave, or sabbatical. LTOs are typically months in duration, sometimes spanning a full school year.
LTOs are significant for three reasons:
1. You build a continuous record at one school. The principal and staff get to see your teaching over a sustained period — not just a day or two.
2. You gain access to the full teacher professional development structure. You'll attend staff meetings, participate in PLCs, and be treated as a regular staff member.
3. LTO teachers are preferentially hired for permanent positions. When a permanent position opens in the school or board while you are on an LTO, you are the most visible internal candidate.
How to get an LTO: LTO assignments are sometimes posted and sometimes filled through direct request. Teachers who are known and liked by a principal are often offered LTOs directly. This is why building relationships in every school you supply in matters so much.
Step 4: Apply Strategically for Permanent Positions
Once you have supply experience — ideally including an LTO — you are a strong candidate for permanent postings. A few principles for the permanent job search:
Apply to the board you're already working in first. Internal familiarity is a real advantage. If you've taught at multiple schools in a board and built relationships, applying internally gives you a meaningful edge over outside candidates.
Target shortage subject areas. If you have teachable subjects or qualifications in shortage areas (FSL, special education, mathematics, sciences), explicitly highlight them even if the posting is not specifically for that subject. Boards know their shortage areas and will factor it in.
Get additional qualifications before you apply. If you have time between supply assignments, completing an AQ course — particularly Special Education Part 1 or an additional teachable — adds concrete value to your file. OCT AQ courses are available online and can be completed in parallel with working.
Write a school-specific cover letter. Generic letters are identifiable instantly. Referencing the specific board's context, any PLCs or professional development you participated in during an LTO, and the specific role signals genuine engagement.
Province-Specific Notes
Ontario
Ontario has the most formalised occasional teacher system. Many boards use a centrally dispatched automated call system (e.g., Aesop/Frontline). Getting familiar with your board's system early saves significant frustration.
Some Ontario boards have recently moved to "self-select" systems where occasional teachers can see and claim assignments through an app. Checking the app first thing in the morning and claiming assignments quickly is a competitive advantage in popular boards.
British Columbia
BC calls occasional teachers "TTOCs" (Teacher Teaching on Call). The same dynamics apply — TTOCs who are known and requested in specific schools are far more likely to receive long-term placements and permanent offers.
Alberta
Alberta uses "substitute teachers" — the pathway is comparable. Urban boards (CBE, EPSB) have large substitute pools and are more competitive. Rural Alberta boards have smaller lists and often have difficulty filling calls — being reliable in a rural board creates a faster path to permanent.
How Long Does It Take?
Typical timelines:
| Path | Timeline to Permanent |
|---|---|
| Shortage subject (FSL, special ed, math) | 1-2 years in a well-served board; as fast as one semester in shortage regions |
| General primary/junior | 2-4 years in competitive urban boards; faster in rural areas |
| Rural or northern board, any subject | Often less than 1 year; chronic vacancies mean positions open constantly |
The fastest path to a permanent contract in Canada is consistently a rural or northern board in a shortage specialisation. If you are willing to teach in a less competitive geography for a few years, you can build experience, qualify for higher-seniority steps on the grid, and re-apply to your preferred board with a much stronger file.

❓ Frequently Asked Questions
How long does it take to go from supply to permanent teacher in Canada?
It varies enormously by province, board, and subject area. In competitive Ontario urban boards, teachers sometimes supply for 3–7 years before landing a permanent contract. In shortage-subject areas or boards with high turnover, the timeline can be 1–3 years. Alberta and BC have seen faster transitions in recent years due to demand. The single biggest variable is whether your teachable subjects are in shortage — math and special ed teachers consistently wait less time than humanities-only teachers.
What is a long-term occasional (LTO) contract and why does it matter?
A long-term occasional (LTO) contract in Ontario — called a TTOC long-term assignment in BC — covers an absent teacher's class for an extended period, usually several weeks to a full semester. It's more than a day-to-day call; you take over the class, set up relationships with students, and often participate more fully in school life. LTOs build your seniority faster, give you experience that translates directly to your permanent teaching interview, and signal to administrators that you can manage a classroom independently.
Does supply teaching experience count toward permanent contract seniority?
In most provinces, yes — though the formula varies. Ontario counts accumulating supply days toward your seniority ranking on the board's occasional teacher list. BC builds TTOC seniority separately from TTF (continuing teacher) seniority, with different preference rights. Alberta treats permanent and occasional teacher seniority differently. The key is to be on the supply list at the board(s) you most want a permanent contract with, and to accumulate days there specifically.
Should supply teachers take every assignment or be selective?
In the early stages — take everything. Consistency and availability build your reputation with administrators, who are the people who recommend you for LTO and permanent positions. As your seniority builds and you're well-known at specific schools, being somewhat selective (preferring schools where you've built relationships, avoiding situations where you've had difficult experiences) becomes more feasible. Early selectivity is a luxury most supply teachers can't afford and that slows the path to permanent.
What makes a supply teacher stand out for a permanent position?
Principals talk to each other and to HR. Being reliable (you show up, you're on time, you manage classrooms well), flexible (you accept difficult assignments), competent (students are engaged, parents don't call), and proactive (you introduce yourself to principals, express interest in the school) are what get you remembered and recommended. Certifications in shortage areas — special education, FSL, technology — add significantly to your value and your priority in hiring decisions.
