WTF are you doing with your money when living at home then? It sounds like FAIL because it is FAIL.
I started working at about 10 or so...I don't remember the exact age, it was a freaking local paper route I used a wagon to deliver papers with. I remember folding them for a long time, loading them up and delivering wasn't so bad...about 10 or so blocks of my neighbors. I'd imagine I was working for peanuts...I think my paychecks were $10-15.
At 12, I (thanks to my dad and my willingness to work hard) I started filing papers at a bank. I made about $6 hr in 1983 and that scaled to nearly $13 by the time I was 16. I wish that continued until my 40th birthday next year

I'd be making millions a year
Anyway they did help me a bit. I bought my first car for $3600 and my dad restored it to about 10x that figure. It really wasn't a bad car though to start (1966 Mustang GT)...in that condition I'd have a nicer car in the parking lot. However, many of my friends had new BMWs and MB's...one of my best friends had a new Ninja 600, Supra Turbo, Porsche 930, Ferrari 328GTS, and even a Cutlass Supreme (don't ask) all during high school...my parents covered gas and insurance until I started college.
Once I was old enough I took on jobs when I could. I partied a lot too, but threw most into savings... At my peak I'd get out of high school early since my grades were good enough to get me into Executive Internship. That was 3 days a week. The other two I worked after lunch to 5, then Thursday through Sunday worked delivery jobs for Chinese food (my tips were my party money, my paycheck went to savings). Then in College while at home the first 3 years, worked my days off in a job I could study at.
In the end my first half decade of college totalled $7k in loans....the last two years not working at all. Post graduation I bought my first house with a buttload down.
You are Canadian so I really can't speak on the norms there. However here, even the best of normal parents are not those you'd want to hang out with every meal (for abnormal parents think more Hef of Playboy or those that just sail on a 200'+ yacht port to port each day buried in old money and even then you'd be missing a lot of dinners I'd bet).
Anyway I am married now, but when I was single and living with parents I'd usually head to a local BBQ place after my Sunday workouts for all you can eat chicken...I met quite a few lunch goer's that day eating alone too. At night I'd eat with the parents, cook by own stuff (usually non-oven stuff though), or go out. Happy hours and eating at the bar was uber profitable...seems a lot of bachelors enjoy that.
The next trick was always 9 times out of 10 asking to go back to my place (not 9 times out of 10 landing any chick I sat next to...just those wanting to go 'home') was explaining I still lived at home. Fortunately those times were less than 6 months at any of the stretches and I could talk about what I was shooting for.
It seems many of today's guys are saving for a house, yet have nothing in savings.
If you are truly in school though and working is too tough with your studies, then you need to be studying pretty much all your free time to prove that point.
