.ca Shopify Store

Curious what you all think about what domain name to choose to start my first Shopify store. So I thought I would create a poll. All of the domain names are fairly suggestive of their niche.

SolarKit.ca
Sitz.ca
AquaDerm.ca
KnifeShop.ca

The goal is to bring in some revenue while I'm busy doing something else and then sell the whole store for a revenue multiple.
