I'm Canadian and I've never heard of half this stuff
To clarify some things
A serviette is made of cloth, a napkin is made of paper.
Timbit is a brand name for donut holes from a donut shop called Tim Hortons (Timmies) of which there are about 3000 in Canada, which means they are literally on every corner everywhere.
Sofa = Couch = Chesterfield
We don't say bonnet here, that's the UK and that only means the hood. The boot is the trunk.
eh is not really a word, it's an inflection like uh or yo and people in Ontario (where I live) don't really say it.
A lot of those differences are because we kept English words or spellings E.G. Zed.
