Hi RBBarnier and welcome to the forum.
Whereabouts in southern Ontario do you live?
If you have any humane societies or SPCA's near you most of them offer low cost spay and neuter services.
I don't live in Ontario but there are others on here that do who might be able to offer you more specific guidance.
