The best Grade 11 courses for engineering are Functions (MCR3U), Physics (SPH3U), Chemistry (SCH3U), and English (ENG3U). Introduction to Computer Science (ICS3U) is a strong add-on for software-leaning students. These four to five courses are not optional extras.
They are the only path to your Grade 12 prerequisites. Ontario engineering programs require Advanced Functions (MHF4U), Calculus and Vectors (MCV4U), Chemistry (SCH4U), and Physics (SPH4U).
Most students do not find this out until Grade 12, when it is too late to fix. This guide covers which Grade 11 courses matter and why the sequencing is so unforgiving. It also shows what real Ontario engineering programs currently publish about admission averages and course requirements.
Quick Answer: For engineering at Waterloo, U of T, McMaster, Queen’s, or Western, take MCR3U, SPH3U, SCH3U, and ENG3U in Grade 11, plus ICS3U for software paths. These courses are the only route into MHF4U, MCV4U, SCH4U, and SPH4U in Grade 12, and every Ontario faculty requires all four on your transcript. U of T’s engineering faculty, for example, requires all five courses with a minimum grade of 70% each. Skipping a Grade 11 science, or taking the wrong math level, can permanently close off your Grade 12 options.
Key Highlights of Best Grade 11 Courses for Engineering
- U of T requires five Grade 12 prerequisites for engineering: ENG4U, MHF4U, MCV4U, SCH4U, and SPH4U, each with a minimum grade of 70%.
- U of T’s competitive range runs high 80s to low 90s for Mechanical and Civil Engineering. It runs low to mid-90s for Computer Engineering, Electrical Engineering, and Engineering Science.
- Waterloo requires English, Physics, Chemistry, Advanced Functions, and Calculus and Vectors for every engineering program, with a minimum grade of 70% in each.
- Waterloo’s competitive average runs mid-80s for Chemical and Civil Engineering, up to low-90s for Electrical and Software Engineering, per Waterloo’s 2026 intake table.
- McMaster’s Faculty of Engineering states that applicants for its 2027-and-beyond direct-entry programs need an 87% average plus a supplementary application.
- MHF4U (Grade 12 Advanced Functions) requires MCR3U as its Grade 11 prerequisite, per the Ontario Ministry of Education’s math curriculum document. There is no shortcut course.
- Waterloo’s Software Engineering program requires a programming course, such as Grade 11 or 12 computer science. This makes ICS3U valuable even where it is not required.
Why Grade 11 Course Choices Decide Your Grade 12 Options
Ontario’s course code system is built on prerequisites. Math and science courses are the strictest of all. You cannot register for a Grade 12 university-stream course without the matching Grade 11 course first. There is no way to test out of it or skip ahead once Grade 11 has started.
This matters because engineering-bound students need four specific Grade 12 courses. MHF4U (Advanced Functions) requires MCR3U (Grade 11 Functions) as its prerequisite. MCV4U (Calculus and Vectors) requires MHF4U, which traces back to MCR3U. SPH4U (Physics) requires SPH3U, and SCH4U (Chemistry) requires SCH3U.
Miss any one of these Grade 11 courses, and the matching Grade 12 course is off the table for that school year.
According to the Ontario Ministry of Education’s Grades 11 and 12 mathematics curriculum document, MCR3U is the university-preparation math course. It leads directly into both MHF4U and, later, MCV4U. Students who take MCF3M (Functions and Applications, a university/college blend) instead of MCR3U cannot move into MHF4U the following year. Fixing that usually means summer school or an extra semester.
The same logic applies in science. SPH3U and SCH3U are the Grade 11 university-stream courses. Their college-stream counterparts do not lead into SPH4U or SCH4U. A student who takes the wrong stream in Grade 11 science effectively removes engineering as an option, unless they make up the course later.
The Five Grade 11 Courses That Matter Most
MCR3U: Functions (Grade 11, University Preparation)
MCR3U covers quadratic, exponential, and trigonometric functions, and it is the single most important prerequisite in this entire pathway. It feeds directly into MHF4U and, from there, into MCV4U. Every engineering program that lists Calculus and Vectors as a requirement is really asking whether you completed MCR3U two years earlier.
Students who struggle with MCR3U often find that the algebra and function-notation skills, not the calculus concepts, are what trip them up in Grade 12. A strong, genuine mark in MCR3U sets up an easier Grade 12 year.
SPH3U: Physics (Grade 11, University Preparation)
SPH3U introduces kinematics, forces, energy, and waves. According to McMaster’s Faculty of Engineering, Physics and Calculus and Vectors marks are scrutinized closely. They predict how ready a student is for first-year mechanics and calculus-based engineering courses. SPH3U is the only route into SPH4U, which every engineering faculty in Ontario requires.
SCH3U: Chemistry (Grade 11, University Preparation)
SCH3U covers atomic structure, chemical bonding, and quantitative chemistry. The University of Toronto’s engineering FAQ page states plainly that all applicants must present senior-level chemistry, SCH4U or equivalent, with no substitute.
Students sometimes assume chemistry matters less for mechanical or electrical engineering than for chemical engineering. It does not. Every Ontario engineering faculty in this guide requires it.
ICS3U: Introduction to Computer Science (Grade 11, University Preparation)
ICS3U is not a strict prerequisite for most engineering programs. It still carries real weight for two groups of students: those interested in software or mechatronics engineering, and those applying to Waterloo Software Engineering. Waterloo’s admission requirements page states that Software Engineering applicants need experience in a programming course. Grade 11 or 12 computer science, or equivalent self-study with demonstrated interest in coding, both count.
Even for students aiming at mechanical or civil engineering, ICS3U builds computational thinking used in first-year courses across every discipline. If you are also weighing Grade 12 options, our companion post on the best Grade 12 courses for computer science goes deeper.
ENG3U: English (Grade 11, University Preparation)
English is easy to overlook because it feels unrelated to engineering. It is not. Every Ontario engineering faculty requires ENG4U in Grade 12, and ENG4U requires ENG3U as its prerequisite.
Waterloo’s admission table lists a minimum 75% in English for Architecture applicants. A strong English mark also supports the Admission Information Form and Personal Profile responses that most engineering faculties now use.

What Real Ontario Engineering Programs Currently Require
Admission averages shift every year based on how many students apply, so treat the ranges below as current context, not a guarantee. All figures below come directly from each university’s own admissions pages, checked in July 2026.
| University | Grade 12 Prerequisites Required | Published Competitive Average Range (2026 cycle) |
| University of Waterloo | English, Physics, Chemistry, Advanced Functions, Calculus and Vectors (minimum 70% each) | Mid-to-high 80s (most programs) to low-to-mid 90s (Electrical Engineering, Software Engineering) |
| University of Toronto | ENG4U, MHF4U, MCV4U, SCH4U, SPH4U (minimum 70% each) | High 80s to low 90s (Chemical, Civil, Mechanical) to low-to-mid 90s (Computer Engineering, Electrical Engineering, Engineering Science) |
| McMaster University | Best six 4U/M courses including ENG4U, MCV4U, SCH4U, SPH4U | 87% minimum average required for consideration under McMaster’s 2027-and-beyond direct-entry model, plus a supplementary application |
Waterloo Engineering’s admission requirements page states there is no absolute grade cut-off for any program. The probability of admission changes from year to year depending on how many students apply. Waterloo’s published intake table lists Software Engineering and Electrical Engineering with a minimum competitive average in the low-to-mid 90s. Chemical, Civil, and Environmental Engineering sit in the mid-to-high 80s.
The University of Toronto’s engineering admissions FAQ confirms that averages are calculated using only the five prerequisite subjects, not your full six-course average. Computer Engineering, Electrical Engineering, and Engineering Science currently sit in the low-to-mid 90s. Mechanical, Civil, and Materials Engineering sit in the high 80s to low 90s.
McMaster is shifting its process, according to McMaster’s Faculty of Engineering. Starting with the Fall 2027 entrance class, students will apply directly to a specific engineering program instead of a general first-year pool. An 87% average plus a completed supplementary application is required just to be considered. McMaster’s engineering pages also confirm that marks in required Grade 12 math and science courses are weighted heavily.
Queen’s and Western both publish similar five-course prerequisite lists on their own admissions sites: English, Advanced Functions, Calculus and Vectors, Chemistry, and Physics. Both schools draw from the same pool of Ontario applicants. The Grade 11 course strategy in this guide applies whether Waterloo, U of T, McMaster, Queen’s, or Western is the target.
Common Grade 11 Mistakes That Hurt Engineering Applications Later
Taking the college stream by mistake in one science. Some students take SCH3U but accidentally register for the college-stream physics course, assuming “physics is physics.” College-stream science does not lead into SPH4U.
Confirm every science course code is the “U” (university) stream, not “C” (college) or “M” (mixed).
Choosing MCF3M instead of MCR3U. MCF3M suits students heading to college diplomas or business programs, but it does not lead into MHF4U. A student who takes MCF3M and later chooses engineering usually has to add MCR3U through summer school, which costs time and money.
Dropping chemistry or physics because “my program doesn’t need it.” Every major Ontario engineering faculty requires both Grade 12 chemistry and physics, no matter which discipline a student later picks. Dropping either science in Grade 11 removes engineering as an option.
Underestimating how much English marks matter. ENG4U is one of the five or six courses used to calculate the admission average at most schools. A weak Grade 11 English foundation can quietly drag down the overall average.
Waiting until Grade 12 to build extracurricular or interview readiness. Waterloo and U of T Engineering both use an Admission Information Form or Personal Profile interview alongside grades. Students who wait until Grade 12 to think about robotics teams or science fairs often scramble for material.
Our post on how to build a STEM portfolio for university covers how to start that record early. Our robotics project ideas for students post gives concrete starting points.
What to Consider Before Locking In Your Grade 11 Timetable
Choosing the “right” Grade 11 courses is not free of tradeoffs, and an honest guide should say so.
Taking MCR3U, SPH3U, SCH3U, and ICS3U in the same year is a heavy course load. These are four of the most demanding university-stream courses in the Ontario curriculum. Stacking all of them in one semester can hurt marks across the board if a student is not ready for the workload. Some students are better served spreading physics and chemistry across two semesters instead.
Course fees and access also matter. If a student’s school does not offer ICS3U, or an elective conflicts with a science course, online or private-school options may fill the gap. Not every family has the same flexibility here. Switching schools or adding a course mid-year has real costs in time and money.
Finally, admission averages shown above are current ranges, not promises. According to Waterloo Engineering’s own admission page, meeting a published average range does not guarantee a seat.
The Admissions Committee also reviews the Admission Information Form and, for some programs, an online interview. Grades open the door. They do not automatically walk you through it.
How USCA Academy Supports Engineering-Bound Grade 11 Students
USCA Academy is an Ontario Ministry-inspected private school in Mississauga offering the full slate of engineering-relevant Grade 11 courses. That list includes MCR3U (Functions), SPH3U (Physics), SCH3U (Chemistry), ICS3U (Intro to Computer Science), and ENG3U (English). Course details for MCR3U are outlined on our MCR3U Functions Grade 11 course page. It lays out the unit breakdown that leads into MHF4U the following year.
Class sizes at USCA run 5 to 15 students, which allows more one-on-one time in courses like SPH3U and SCH3U. A shaky Grade 11 foundation in these courses causes real problems two years later in SPH4U and SCH4U.
Not every science ties to one future major. For more on why all three sciences matter, read our post on why biology, chemistry, and physics matter in a Grade 11 class in Canada.
Students unsure whether they want engineering or a biology path can also review our Grade 11 college-preparation biology course, SBI3C.
USCA also runs a tutoring program in math, physics, and chemistry. Many engineering-bound students use it alongside their regular Grade 11 courses to strengthen the marks that Waterloo, U of T, and McMaster weight most heavily. Students working on physics or math specifically can look at our physics tutor Mississauga and math tutor Mississauga pages.
Students needing help across all three sciences can review our science tutor Mississauga page. Families planning the full Grade 11 to Grade 12 sequence can see available courses on our Grade 11 program page and our courses page. Families can also map OSSD (Ontario Secondary School Diploma) requirements against university prerequisites through our university preparation program.

Frequently Asked Questions
1.Do I need Grade 11 biology (SBI3U) to apply for engineering?
No. None of the Ontario engineering faculties in this guide list Grade 11 or Grade 12 biology as a required course. Biology can still be a useful elective for biomedical or environmental engineering interests. It does not replace physics, chemistry, functions, or English in the admission average
2.What if my school does not offer ICS3U in Grade 11?
Most engineering programs do not strictly require ICS3U. Its absence will not disqualify a general application. It matters most for Waterloo Software Engineering, where a programming course or documented self-study is expected. If your school does not offer it, look for an online Ontario-accredited option or plan to take ICS4U in Grade 12 instead.
3.Can I switch from the college stream to the university stream after Grade 11?
Generally, no, not directly. University-stream Grade 12 courses require the matching university-stream Grade 11 course as a prerequisite. A student who took the college stream usually needs to complete the university-stream Grade 11 course afterward. That often means summer school before Grade 12 university-stream courses become available.
4.Does taking all four core Grade 11 courses in one semester hurt my marks?
It can, depending on the student. MCR3U, SPH3U, and SCH3U are all demanding university-prep courses. Some students do better spreading physics and chemistry across two different semesters, even if it means a slightly different four-year plan.
5.Is a 90% average enough to get into engineering at Waterloo or U of T?
It depends on the program. Mechanical and Civil Engineering at U of T currently sit in the high 80s to low 90s, so 90% is competitive there. Computer Engineering, Electrical Engineering, and Engineering Science sit in the low-to-mid 90s, so 90% may fall below that range.
6.How is McMaster’s application process changing for future entry years?
Starting with the Fall 2027 entrance class, applicants will apply directly to a specific engineering discipline rather than a shared first-year pool. They will also need an 87% average plus a completed supplementary application to be considered.
