Andrew Scheer really doesn't want to talk about abortion. Neither did Stephen Harper - 2019-05-24
Based on what he said during the Conservative leadership race, Scheer's answer to those specific questions would seem to be "yes." Those campaign comments suggested that, while a Scheer government would not itself introduce abortion legislation, Conservative backbenchers would be free to do so and Conservatives would be free to vote their "conscience" on those bills or motions.
That roughly corresponds with official Conservative policy on such matters and relies on a legitimate parliamentary distinction between the MPs who are part of the government (cabinet ministers, parliamentary secretaries) and those who are not (the backbenchers who are members of the governing party, but not part of the executive).
If that's still Scheer's position, he might just say so. But he also wouldn't be the first Conservative leader to have second thoughts about indulging the backbench.
