jQuery Autocomplete City & Country based on zip code

Question

I was wondering if anyone knew a good service for City and Country Lookup by postal code, I was using the ziptasic plugin from jQuery, but it only supports the US and I need to search within Canada, both would be great. I know google maps API is another method but I dont even know where to start.

Any help would be great!

Thanks
