Hi Hanan - welcome to the Canada sub-forum.

If you search here (use "advanced search as search is disabled) you can find places to shop and online shopping.

You can make almost any restaurant work for LCHF if you are very clear with the server what you want. I sometimes go to White Spot for breakfast and have Eggs Benny - hold the English muffin and hash browns, sub in tomatoes.

Ask away here for things specific to Canada and in other sub-forums for more generic things like what supplements to use.

Best of luck on your WOL.
