Vodka prices will differ in each province but the choices will be good, however the real treat (as already posted) is the Beer, especially the local micro-breweries.
Although the liquor prices may shock you, so will the whole trip. Good shock though!! We spent three months from Manitoba to Newfounland and could have spent the whole time in two provinces. Have a great trip as I'm sure you will.
I follow your Mexico blog and wondering if you will include your Canada trip, or are you starting a new one. Whatever, really enjoy your Mexico input and hope to follow you across Canada.
