Mom says "sizzuhs" (something like that) for "scissors," and some weird "kw" sound at the start of "coffee" so that it sounds kinda like "quaff-ee." Does that make sense?
I used to work with a woman who is originally from the Bronx - her accent is very similar to your description of your mother's. I occasionally like to tease her by saying, "Aw, look at the poor dog with a thorn in its sore paw, sitting in a four-door car" in her accent.
Going through the maps:
1. Care-a-mel.
2. "e" as in "set."
3. "Bo-wie", like the singer.
4. I guess I pronounce it "cray-ahn," though by this person's criteria, I pronounce it to rhyme with "dawn." Maybe I'm pronouncing "dawn" incorrectly?
5. Loy-er.
6. Cole slaw. I've never heard it just called "slaw."
7. "You," unless I'm in Atlanta, where I mysteriously start texting friends and saying, "Where y'all at?" (I'm not sure how I picked that up. My ex-bf, who was born and raised in Tennessee and lives in Atlanta, doesn't even say "y'all.")
8. May-uh-naze.
9. Pa-JAM-as.
10. Pee-KHAN.
11. Pop.
12. Crayfish.
13. Roundabout.
14. Sir-up.
15. Sub.
16. Water fountain.
17. Running shoes. This may be a Canadian thing, as it didn't even make his map.
18. Highway, though if there's a different word in the name of the road, I would use that instead. For example, we have such a road here that's called the Gardiner Expressway. But even the Macdonald-Cartier Freeway, I call a highway - then again, I don't know anyone who calls it the Macdonald-Cartier anything. It's just "the 401."
19. Sunshower - though I've never seen it written as one word. I'd always assumed it was "sun-shower." (And there's somewhere where it's called "the devil is beating his wife?" Really? I've never heard that one.)
20. Toronto, of course. The Centre of the Universe.

21. I've never heard of a drive-through liquor store - but here, liquor is only sold in government-run stores (though there are a small number of specialty wine stores).
22. All of the following rhyme: airy, berry, Barry, carry, dairy, fairy, ferry, Gary, Harry, Jerry, Larry, merry, marry, Mary, Perry, tarry, terry, very.
