What’s behind the secessionist movement in the Canadian province Alberta?

Secessionists in Alberta have submitted nearly 302,000 signatures to election authorities, exceeding the 178,000 required for a referendum on independence from the rest of Canada. The signatures were formally submitted earlier this week, marking a historic step in Alberta's push for greater autonomy. If verified, a referendum would ask voters if they agree that Alberta should cease to be part of Canada to become an independent state. However, a court ruling and a legal challenge from Indigenous groups have stalled the verification process.
