How many credit cards are in my wallet

I stay with my principle of minimalism. use max 3 cards in my wallet to keep life simple.

For myself:

• Visa card: CIBC Aventura Infinite visa card ( This is my primary card with lots of perks )
• Master card: PC World Elite master card ( used for NoFrills grocery, Esso gas and Costco)
• Stay-at-home card that I used for recurring bills only: Tangerine cash back master card, which I can take advantage of 2% cash back offer for recurring bills.

For my wife:

• Visa card : CIBC Aventura Infinite visa card ( secondary card )
• Master card: Roger World Elite master card ( 1.75% cash back on everything)

For my kid:

• Visa debit card: Bank card
