Each of the approved policies from IdeasLab and the regional policy meetings will be divided into general categories, typically along the lines of foreign affairs, justice and crime, economics, and social policies. At the policy convention, there will be one room for each of these general categories and the policies that are passed within these break-out sessions will make it to the plenary session.
The plenary session takes place on the second day where every delegate gets to vote on all the approved policies from the break-out sessions. In order for a policy proposal to pass, it must receive an overall majority of 50% + 1 of all voting delegates in the room and have a majority of the delegates from 7 provinces and territories also vote for the proposal (known as a double majority).
Let's continue with our example policy proposal to strike down Policy No. 65 (A Conservative government will not introduce legislation to regulate abortion). After being approved on IdeasLab or in a regional policy meeting, the policy would go to a break-out session at the policy convention (most likely one on health and social issues). That break-out session would need a majority of pro-life delegates at the time of the vote of the policy in order for the policy to go to the plenary session.
Assuming that happens, the policy would then require a simple majority of the approximate 3,000 voting delegates at the plenary session and a majority of the delegates from seven provinces or territories. In this example, if the policy proposal receives 1,600 of the 3,000 votes cast and the approval of the majority of delegates from Alberta, Saskatchewan, Nunavut, Ontario, Prince Edward Island, Newfoundland and Labrador, and New Brunswick, then the policy would pass.
If the policy proposal received 1,600 of the 3,000 votes cost but only received the approval of the majority of delegates from British Columbia, Alberta, the Northwest Territories, Quebec, and Nova Scotia, then it would fail.
If the policy proposal received 1,400 of the 3,000 votes cast and received the approval of the majority of delegates from Yukon, Saskatchewan, Manitoba, Newfoundland and Labrador, Nova Scotia, Prince Edward Island, and New Brunswick, then it would fail.
