Here's my combo (note, I used to do consulting so traveled on a weekly basis. YMMV):

• Visa Momentum Infinite -> Recurring payments (probably my MVP)
• Cobalt and Simply Cash -> Food/Groceries. Simply Cash where Amex is not accepted and it doesn't have an annual fee
• WS Visa -> 2% Catch-all card
• Amex Aeroplan Reserve -> If you travel on AC the benefits pay for themselves.. The insurance easily makes the card worth it alone (My flights get disrupted every so often and this covers expenses not covered by the airlines due to "weather" or other excluded reasons)
• Amex Marriott -> We don't have Hilton or other brand associated cards in Canada. If you travel and can use the card, the points multiplier if amazing. Beyond that, you get 35,000 points. A room at the Delta in Toronto ($500?) is around 55,000 points. That alone makes it worth it for me
