Going back to school after 25 is common in Ontario. You may not need a high school diploma to start, and you can fund studies with OSAP or other programs. This guide shows the fastest entry routes, the money options that actually cover costs, and which colleges make life easier for adults with jobs and families.
Admission pathways (even with no high school diploma)
Direct-to-college as a “mature student.”
Ontario public colleges can admit applicants who are 19+ without an OSSD if you meet program prerequisites through testing or upgrading. Many diplomas accept “19+ with mature status” plus proof of English/math readiness.
ACE (Academic and Career Entrance) = Grade 12 equivalency for college/apprenticeship.
If you need missing credits, the ACE certificate is recognized across Ontario colleges as a high-school equivalent for admission and apprenticeships. Programs run in-class or online, often tuition-free for Ontario residents.

College academic upgrading & pre-programs.
Colleges run Academic Upgrading/ACE courses (English, math, biology, chemistry) so you can meet program prerequisites, usually with flexible intakes and adult supports. Examples: Humber, Seneca, Conestoga, Fanshawe.
Universities treat “mature” differently.
If you’re aiming for a degree, check each school’s rule—e.g., one Ontario university considers applicants 20+ and out of full-time high school for ≥2 years for mature admission. Requirements still vary by program.
Quick comparison: find your best on-ramp
- Direct entry (19+ mature status): Fastest if you already have strong English/math.
- ACE certificate: Best if you need a recognized high-school equivalent for college/apprenticeship.
- Pre-programs (Pre-Health, Pre-Business): Good if your target program needs specific grade-12 courses.
- University mature entry: Good for degrees, but expect extra proofs (tests, prerequisites).

OSAP for mature students (and other funding)
Age is not a barrier.
OSAP is open to Ontario residents who meet citizenship and program rules—there’s no maximum age. Funding depends on course load, income, and family status.
Full-time vs part-time OSAP.
- Full-time OSAP: 60%+ course load (or 40%+ if you have a permanent disability).
- Part-time OSAP: 20–59% course load. Part-time OSAP mainly covers tuition, fees, and books—not day-to-day living costs.
Better Jobs Ontario (formerly Second Career)
Need-based grant. You can apply for up to $28,000 for training ≤52 weeks, and up to $35,000 if the program is longer than one year. Certain categories (e.g., disability-related supports) or exceptional cases may exceed $28,000 at ministry discretion. Covers tuition, books, other instructional costs, transportation, and a basic living allowance (up to $500/week); additional supports (childcare, LBS/language training) may be available.

Micro-credentials with OSAP
University “mature student” rules vary by institution. Examples:
- York University: usually 20+, out of full-time high school ≥2 years, and <1 year of post-secondary attempted. Meeting minimums doesn’t guarantee admission.
- Toronto Metropolitan University (TMU): 21+ by Dec 31 of start year, away from formal education ≥2 years, plus program prerequisites (typically 70%+).
- University of Toronto (UTSC example): treats admission based on academic background rather than age; UTSC flags 21+ by Oct 1 as a common mature-applicant pathway for some programs; check exact faculty/program rules.
- Carleton: Canadian citizen/PR, away from full-time studies ≥2 years, and no full-time post-secondary to date.
Worked example (simple numbers):
Two ACE courses (part-time) at a college, $350 each = $700 tuition + $250 books = $950. Part-time OSAP can cover school costs; plan your living costs separately since part-time OSAP doesn’t fund rent or groceries.
Balancing work, family, and study
- Choose the right course load. If you work 30–40 hours/week, consider 1–2 courses (20–40% load) first term; move up once you find your rhythm.
- Stack flexible formats. Look for evening, weekend, online, or hybrid delivery; many ACE and upgrading classes offer these modes.
- Use campus supports built for adults. Ask about tutoring, childcare bursaries, prior learning assessment (PLAR), and academic advising—many colleges have dedicated mature-student hubs.
- Budget weekly, not monthly. Tie study blocks to your shift schedule; set a fixed “family night” to protect time at home.
- Protect commute and break time. Turn bus rides and lunch breaks into flash-study sessions with cues (Anki, formula sheets).
Colleges with strong supports for mature learners (examples)
These Ontario public colleges publish clear mature-applicant pathways, ACE/upgrading, and adult-student services:
- Seneca (Toronto): 19+ mature entry; Academic Upgrading; mature-student advising.
- Humber (Toronto): Academic Upgrading (ACE equivalencies), online ACE options.
- Conestoga (Kitchener/Cambridge): Many diplomas list “OSSD or 19+ with mature status” plus upgrading options.
- Fanshawe (London): Mature applicant pathways and upgrading to meet prerequisites.
(These are examples; every public college in Ontario offers some mix of mature entry and upgrading. Pick based on your program, campus, schedule, and supports.)
Step-by-step checklist
- Pick a target job title → match the required credential (certificate, diploma, or degree).
- Find 2–3 programs at Ontario public colleges or universities that lead there.
- Check admission route: direct mature entry vs ACE/upgrading vs pre-program.
- Map funding: Full-time OSAP or Part-time OSAP; consider Better Jobs Ontario and OSAP for micro-credentials if relevant.
- Apply via ontariocolleges.ca (for college) and book any placement tests/upgrading.
- Build a weekly plan with work, childcare, study blocks, and a “no-study” family window.
Key takeaways
- You can return after 25 without an OSSD using mature student routes or ACE.
- Pick full-time OSAP (60%+) or part-time OSAP (20–59%) based on your schedule.
- Better Jobs Ontario and micro-credential OSAP can fill gaps for career pivots.
- Choose colleges with adult supports: upgrading, flexible delivery, advising, and PLAR.
