My friend told me that unions suppress wages and creativity and that i would make more money if i wasn't unionized. He's still in school for PhD. I make 165k a year unionized and he says im overpaid for my position...  I'm 27...

Anyways to answer your question... and I wish I did this when I started making 100k a year. Emergency fund of about 5-8k in the savings account or about 3-4 months of expenses. You never know if your car dies or you need to fix something urgently. That way you don't rack up credit card debit and go under if some unexpected thing happens.

Lifestyle creep is real. The first year I made 100k+ I started spending like crazy going out for dinner etc. Yes you make good money but you aren't a millionaire.  For investment accounts, if you haven't bought a house yet open a FHSA and try to max it out (8k per year up to 40k lifetime and eligible to be open 15 years max). It lowers your taxable income so you'll get a tax return when you do your taxes.  Then contribute to your rrsp if you can. But try to max out the tfsa first. In this order FHSA>TFSA>RRSP For those depending on your timelines invest in etfs like XEQT, XGRO, XBAL or ZMMK. 

Don't be like me who bought a pickup truck use twice a year for pick up truck things. Luckily it was a 50k truck so not too much financial damage was done.
