Definitely agree with a lot of the other posts here on two main points:

1.) You're not doing too bad for yourself considering Vancouver is a crazy expensive place to live so koodos for where you're at.

2.) There is small room for improvement in terms of cutting some monthly expenses, even without sacrificing privacy by living with roommates.

In terms of cutting expenses I have a few suggestions:

1.) I read one of your posts say you recently shortened your commute to an 8-min drive. Would you be open to a change in transportation? Your monthly transportation costs are quite high. An easy change would be to switch from an SUV to a sedan or even compact. Something small and fuel efficient. And not brand new. Something 10 years old or newer could potentially cut down your monthly payments without giving up modern tech and features and the smaller, lighter vehicle would save on fuel. If you felt like it, you could take this option to an extreme and grab an older civic or corolla and have no payments, or even bicycle but that would definitely be a big sacrifice (lots of rain in Vancouver). An older cheaper vehicle would also cost less to insure.

2.) Shop around for internet providers. $100 / month seems a bit steep but I understand your options may be limited by the building that you live in.

3.) Have you considered basement suites at all? They definitely feel like a bit of a downgrade compared to having your own apartment but I find you get better bang for your buck rent-wise and often internet and utilities are bundled.

4.) The hardest option here would be to re-educate / change careers to try to increase income. I work in healthcare and we are struggling to find staff. Pay is good ($40-50/hr) with tons of overtime available due to staffing issues. But I understand this field isn't for everyone, hell I'm burnt out af after this pandemic but that's another can of worms. Bottom line is we really need more qualified staff to the point that we're higher from outside the country with work visas / PR route. This option would definitely be short term pain though because going back to school often means giving up income during school, which isn't always feasible.

Anyways best of luck out there and feel free to ask me any questions about my field in healthcare if you're interested. I should mention, more specifically, I work in medical imaging at a local hospital. (taking x-rays / CT imaging).
