Can a major shareholder sell the company (a regular business, not an Inc)?

Assuming it is a normal business in Canada (registered business partnership - not an Inc.), can a major shareholder decide to sell the company and all its shares of other shareholders, if he/she owns over 50% of the shares? What if other shareholders don't agree? Also, say a decision was made to sell the company by the major shareholder, who values the company and the price of each share of the shareholders (i.e. 1% worth in Dollars)?
