If you are serious about applying for the super visa, then you need to read through the application guide to make sure you understand all of the requirements and don't end up having your application refused due to mistakes on your part.
You can find the application guide here:

Here's what the application guide says about insurance:
proof that you have private medical insurance valid for a minimum of one year from a Canadian insurance company and that:
- covers health care, hospitalization and repatriation,
- provides a minimum coverage of $100 000, and
- is valid for each entry to Canada and be available for review by a port of entry officer.
