20 YO Needing advices for where to start (Canadian?

Hello I've been lurking here a while and I now need advice, Coming from a paycheck to paycheck family I never understood investing and savings,

I'm 20 Yo living In Québec, Canada and landed a 40k/year job that offers a pension plan and benefits.

I get to take home 2500/mo after deductions. Both me and my GF of 6 years have 0 depts and pays 900$/mo total for rent and phone/internet bills that we split 50/50. Food is around 300-400$ (Kind of a crafts beer enthousiast 😅) Also planning on upgrading our beaters to a more recent car that would suit eventual kids

Where do I start to start putting money aside with home ownership in the next 5 years in mind?
