I would not agree because peremptory challenges provide an accused person with the ability to challenge the fairness of what is transpiring. We know that the jury pool and panels are constituted by the provincial governments. They are randomly constituted and they ought to be randomly constituted. The accused has to have some say in who ultimately ends up in the pool. Just by looking at the individuals, there could be any number of reasons why someone can feel it proper to challenge a person peremptorily.
More importantly, there is a residual ability for prejudice to surface during the challenge for cause process. As potential jurors are being challenged and they're being asked if they're racist.... These are situations in which people who may not have been acrimonious to your cause or your opponents cause actually develop that level of prejudice. It would provide an opportunity to use a peremptory challenge in a proper way.
