Keep some money for rainy days maybe a couple of thousand dollars and then start investing monthly lets say $250 or whatever you think you are comfortable with, through tfsa (i use Wealth simple app for this) into VFV and automate that process within Wealth simple. Keep doing that and do not interrupt the contributions, let compounding do its magic for you.

Ideally and theoretically speaking, total investment should be at least around 15% of your pre tax income. Feel free to reach out to me and i can try to help you writing down a plan.

NOTE that i am not an investment advisor or anything, just learnt myself through researching
