My sides. A senior event. At that age the only one you're competing against is yourself.

The Canadian Powerlifting Union announced a gender self-identification policy earlier this year that allowed athletes to participate in women’s competitions on the basis of self-declared gender alone.

Yeah that's bullshit there's a reason the rules set by all other organisations involve something along the lines of a minimum of two years on HRT. Noone at all anywhere is claming that the act of identifying as a woman, alone, reduces muscle mass.
