I can offer a couple of comments on this, if I may.
At a national level, it's really important that we work together with organizations like the Canadian Teachers' Federation to better train, equip and support their members, educators across the country, to provide this type of foundational education, and to start early and educate early.
So much of this is fuelled by the kinds of norms and socialization we teach boys and young men from a very early age about always being in control, always fighting back, standing their ground and not accepting any emotions other than anger. Rather, they need to accept a full range of emotions, to seek help when needed rather than keeping it in and to ask for help.
Without those kinds of early skills, boys and young men end up growing up not knowing how to deal with their feelings of loss, rejection and anger, and they end up using violence instead.
