Ballet has had a significant influence on dance in Canada. Canada is home to many prestigious ballet companies located across the country. Modern dance is also popular, with several Canadian companies performing this style. Canada additionally hosts hundreds of Ukrainian dance troupes and other immigrant dance communities that preserve their traditions. Native dance has deep roots in Canada, with Northern American Indian tribes influencing modern Pau Wau events - multi-hour celebrations featuring circle dancing to drum music that bring both Native and non-Native people together.
