I relocated to the
UK over a year ago and brought (or will ship) over some expensive appliances that are electric but not electronic such as a sewing machine or electric toothbrush- these appliances can be used with an adapter and transformer. I bought a laptop, mobile, telephone, TV and digital radio here and will probably buy a car over here although public transport, even outside of London, is pretty good. (Get used to turning appliances, etc on and off at the wall over here, by the way.)
Things I miss...decent salad dressing (Rene's garlicky Caesar mmm), shake and bake, tylenol extra strength, neo citron. You can probably get a version of most everything (except for shake and bake) but it won't be as tasty or as effective. I haven't had a decent pizza or sushi (if you can find it) in months. Don't know what to advise about the pizza- I think that you can get good pizza if you spend a heartbreaking £20. Maybe, load up before you leave Canada. As for the sushi, I am thinking of cutting out the middleman and getting one of my relatives to send over some sushi making supplies. I haven't looked for peanut butter so can't report on that.
The have donairs here (called donner, presumably after Santa's reindeer). They are a bit dodgey- avoid them. If you are moving to London, make your way over to the Edgeware Road for some shwarma (Helen's) and you'll never contemplate a 'donner' again. Get used to fish and chips. It will take sometime to find a chippy (north) or fish bar (south) that uses good fresh fish and doesn't keep everything under a heat lamp. You'll get used to mushy peas, too. Sandwiches are called cobs in the midlands, baps in the south (I think) and rolls in the north and Scotland). Your pants are your trousers and your underwear is your pants. Your purse is your handbag and your (woman's) wallet is your purse.
I am way off topic but I hope that this has been helpful.
