Your kid needs a place to sleep, food (breastmilk or formula) and clothing/diapers. Everything else is extra.

For sleeping, if you're in a pinch, your kid can always sleep in a box.
Case in point (excuse the Jets paraphernalia, we were in Winnipeg visiting family):
Everyone is just so different, it's hard to advise - my kid drank formula/breast milk right out of the fridge, dead cold, from the time she left the hospital. We never used a wipes warmer, we never used a monitor. Our stroller was a great buy second hand, same with our crib and change table. We borrowed a swing, received a bouncy chair for free - those types of things are easy to find on kijiji. We never decorated a nursery - heck, our kid's crib was in the den, next to the wine fridge for the first 8 months of her life (when she wasn't sleeping in a box).
I'm a huge fan of babywearing and recommend a soft-structured carrier (such as a Boba, Ergo or Beco) and/or a ring sling for the wee ones. Don't bother with a wrap early on, it's easy to get frustrated and overwhelmed. Bjorns suck aren't ergonomic (even though they say they are), don't get one. Babes in Arms in Bridgeland is an AMAZING place.
Congratulations and all the best.
