There are hundreds of local and regionally based Canadian blues bands and performers which perform mainly in small venues in their home city or town. A much smaller number of Canadian bands and performers have achieved national or international prominence, due to the sales performance of their recordings, acclaim from blues music reviewers and performances at major festivals in Canada, the US, and Europe. These notable bands and performers are supported by a broader Canadian "blues scene" that also includes city or regional blues societies, blues radio shows, blues festivals, blues clubs and informal blues "jam sessions".
