Hi Denise, it's been a long time since I've looked in to the at home plan, but it used to be that when you signed up, they mailed all of the materials to you. But you have to live in an area that doesn't have meetings available. Here is a link, but not sure if if covers Canada -

These days if you sign up at a local meeting, you get a calculator as part of your package. They don't use sliders any more since they now factor carbs, fat, protein and fiber in to the equation and a slider isn't possible to calculate.
They are pushing e-tools and mobile usage a lot more than they did in the past, and unless you really wanted the paper materials, you'd get everything you need with the online program. Good luck!
