LCBO API was created by me, Carsten Nielsen, a software developer from Toronto, Canada. I built it from the ground up using some of my favorite tools, you can read more about those in the FAQ.
The goal of the service is to provide developers with an easy way to create intelligent applications that take advantage of the unique benefits that come with having a single provider of alcoholic beverages in a large geographical area.
The API is intended to provide data to mobile and web applications, an example of such an application is LCBO Search.
If you plan on performing hundreds of queries per second for uses such as data analysis then you should download the entire dataset and perform these operations yourself. Datasets are made available upon every successful crawl and can be downloaded as often as necessary.
I would love to hear about how you are using the data or API. I would also love to hear from you if you want to do something with the data but are not sure how. You can reach me through Twitter, and by email.
