Agree 100% with all that Sina said above.

Agreed. The angled is rather dated.

Yep, put the wood in the kitchen too, any other way would look disjointed. You won't regret it.

Another vote for all hardwood. I would install some toe-kick heaters for a heat source in the kitchen.

I live and build homes in Canada, Toronto to be exact so I understand the cold. But tile is colder than hardwood so the argument doesn't really hold up plus you can do radiant heating under hardwood if you really need too. You will not regret running the hardwood throughout, but IMO you will regret not replacing that old tile while you have the chance.

This is what we did and I love it, it could work for you, just differen shape

I grew up in a country where it gets -35C and our wood floors (no basement) were never cold. Only the tiled areas had in floor heating. Your kitchen will appear larger with the same flooring continuing through the space.

All hardwood!

We have that angled transition in our kitchen /family room and we can't wait to remove it and put all hardwood on the whole first floor! That's our next project :)

All hardwood- just keep going!! Do it now &know regrets later on down the road!
