Hello,
I live in Canada as well, before starting, I called many centers with IP, some of them had ridiculous charges from opening a file (like that would cost money) to putting you through their datasheet or whichever stuff they created, I kept on calling until I found one who told me that she doesn't charge for the consultation, nor for the weigh in nor for anything else except for the food I buy and vitamins I buy, so I went there.
I chose not to buy the IP vitamins, since I printed the sheet explaining about the supplements I should have (which I attached it for you if you'd like to see it) and preferred to get my supplements through Costco and local pharmacies which saved me a lot of money.
I only bought my IP food from the center, until about 2 1/2 months on program where I saw that many are using alternatives with great success, so I decided to do that, I read a lot about nutritional values (also attached is the sheet with this info for you) and started to compare products, I ordered through proteinwell.ca and through nashuanutrition.com, bought some bars from local pharmacies and powder protein shakes.
You can totally do it by yourself to save money. The decision is yours, you have to see what suits you best, if you really need the support of a center or if you'd like to do it alone.
Good luck
