Canada’s premiers tight-lipped on constitutional changes in Alberta referendum

Smith's four proposals, three of which would likely require the support of seven legislatures representing over half of Canada's population (known as the 7/50 rule) and Parliament to implement, are among 10 questions she's putting to Albertans on Oct. 19.

Albertans will vote on several proposals, including three of which would likely require the support of more than half of Canada's legislatures.
