I found instant bisto gravy.

We are still trying to work out what we miss from England and what we/friends can bring across. I miss pork and lamb stock cubes and especially Bisto gravy, which I discovered today - I can get Bisto in Saskatoon. In England it is 2 for £2 in Saskatoon's English shop it costs $7 (only three and a half times the price!)

When it comes to food the canadian borders have a policy. "Declaring is the Law - Be sure . . . declare everything."
"Canada has complex requirements, restrictions and limits for the importation of meat, eggs, dairy products, honey, fresh fruits and vegetables and other food from around the world. You can avoid problems by not bringing these kinds of goods into Canada."

Canadian law requires that you declare all food, plants and animals and related products that you bring into Canada. Many travellers fail to declare things like meat, animal hides, live birds, plants and fruit.

So as far as I can work out No meat, dairy, honey or fruit, so how about meat gravy? I am hoping I understand the website correctly and as it is processed it is fine. Therefore normal priced gravy.
