Which Canadian Credit Card?

[Ryvax]

So I want to switch my credit card.  Right now we have a TD Aeroplan Visa but since moving closer to home, we don't fly anymore....

So my groceries are done Once a month at Costco, NoFrills 3 times a month, All gas purchased at Canadian tire for the CT money at the moment, may switch to Costoco.

So.... CT Master card VS Costco Master Card VS PC Financial Master Card or a better option?

Every card review site doesn't take into account where we actually do our spending.

We use our card for everything and pay it every pay day.  We could always get all three as there are no fees.

What do you guys think?

I applied to scotiabank momentum visa infinite
It has 4% cashback on groceries and gas, 2% on recurring transaction and 1% on everything else.
On top of that, you can get $100 for free by applying through their affiliate.
I described the process here:
