Photographing for EDM shows in Toronto Ontario

I was wondering how one could have an opportunity to photograph (any) EDM shows in Toronto Ontario? So far I’ve photographed San Holo (directly through management) , Mesto (through a small promoters company) and Caribou. I had Tinlicker too but wasn’t able to make the trip sadly. (Again through management) I know most shows are put on via INK or live nation and I assume it’s difficult to get through to them. Any help is much appreciated.

Thanks.
