I am bringing a Mandevilla plant indoor for the winter (I live in Montreal where we get lot's of snow) I am told that I should be treating my leaves and also my soil against bugs, ants etc. What should I use to treat the soil?

There are a number of things that you can use for this. I prefer organic in almost anything I do, but there are chemical methods as well.
I like oils such as: Rosemary, lavender, garlic, clove, and neem... All make wonderful, and safe pest controls that you can mix, spray or water into the plant without hurting it.
Here is a link to a collection of articles that will help you find other methods for controlling insects: https://www.gardeningknowhow.com/special/organic/
