Canadian breakfast cereals?

You'd think with all the cereals we're producing, it'd be ubiquitous, but all the stuff at the grocery store was either Kelloggs, Kraft, or General Mills.
I think Shreddies are made in Canada, but owned by Post?

There seemsto be a few more options out west than here in QC.
I already get granola from a small local place which is great, but surely there's a Canadian version of corn flakes or rice krispies or whatnot somewhere.

I'm also open to just making my own.
