If you're carrying something from the garage in the back to the car in the front either go around the outside of the house, so you don't track dirt through the inside, or pull the car around to the back to load there.
I'm also Canadian and am horrified at the idea of shoes in the house. Even my kid's 800 student school makes all kids bring an extra set of indoor runner to keep at school. The kids have to change shoes every time they go in/out for recess. If they wore their wet boots inside all day the school would turn into a swamp. I've even been to dentists that had a similar set up. Leave your wet boots on the tray at the door. You walked to the exam room in your socks.
If the people you live with won't take their shoes off then your job of cleaning the floor becomes easy. Just make the shoe people wash it. They'll get the idea real quick. Not only does wearing shoes in the house make the floors dirty, it also wears them out a lot faster. All the dirt acts like sandpaper.
Okay, now I'm curious. Are indoor shoes in schools not a thing everywhere???
OP, I'm sorry if you are truly committed to wearing shoes in your house and the rest of us have just kind of rendered your thread useless for you.
I really, really encourage you to at least try not wearing indoor shoes in your kitchen at least. It would drive me absolutely batty to have to mop my kitchen floor every time it gets a little wet while we're in there.
I honestly never mop my kitchen floor, and I'm a total neat freak. Water spills on my white tile floor too, obviously, but it just evaporates and never leaves any marks.
I run the robot vacuum almost daily too, so there's no dirt or dust buildup for the water to blend with, which really helps.
I have the same tile at my front hallway, where we do walk with outside shoes, and it is always visibly much dirtier than the kitchen with the same tile. I do Swiffer mop that small section about once a week.
It's unreal what a difference there is. Outdoor shoes are filthy.
