Hi Newby, can I assume by New West you mean New Westminster? Geographic location is extremely helpful in recommending places to shop and other resources since they vary from place to place.
Regardless... my mom Shirley (Viola on this site) does the tax thing because she buys a lot of gluten-free product. I don't buy much so I don't bother. I will let her know about your post and perhaps she can explain it for you. She's also in BC and can probably direct you to gluten-free shopping better than I can.
Most large supermarkets have a Natural Health food section which usually include many gluten-free products. Personally, I have never been a big bread, cereal or pasta person so I don't miss any of it. Although I have to say that the brown rice spaghetti is awesome!! I'm enjoying my hubby's spaghetti sauce more than ever!
Re: restaurants... YES worry about salads, DO tell them that you can NOT have any croutons, etc. Ask to read the labels of the salad dressing for yourself!! If they do serve you a plate that has toast, croutons, dinner roll etc. be sure to let them know that simply removing the offending portion is NOT enough! The crumbs left behind will make you sick.
If you look for my second post in British Columbia, I talk about my Celiac Survival Kit... you may find that helpful if you eat in restaurants a fair bit.
Basically reading through the many posts in this site will give you amazing insight. Some of it will scare the crap out of you too!
Some of it may make you feel fortunate, since there are so many that suffer so much!
I will mention to Mom that you are interested in tax info. In the meantime, enjoy!
