Computer science vs Engineering
Same columns, no opinion about which is better for you. On typical Ontario figures, Engineering is ahead by year 10 ($486k against $482k), because it pays more per year once you are working. The gap is before tax, rent and loan interest, which hit both routes. Computer science costs $2,000 less to get into. Job Bank rates demand higher for Engineering in Ontario right now.

Earnings by year, roughly
Before tax. Years in school show as "school". Medians rise from the starting figure to the year-5 figure, then stay flat.
Computer science
A day looks like: Programming, algorithms, math; project work; ideally two or three internships.
What stops people: Admission averages in the 90s at top programs; internships are now essential and hard to get.
Downside: Entry-level hiring has cooled sharply. Outcomes are split between graduates with internships and those without.
Engineering
A day looks like: Heavy math and labs for four years; co-op terms in industry. Specialise in second year.
What stops people: Admission averages of 88–95 at the major schools, and a brutal first year.
Downside: Five years if you do co-op, which you should. High tuition. Roughly a fifth of students switch out after first year.
