Are DNR’s still followed if it was a suicide attempt? Can you sue if they ignore it after an attempt?

[everlastinghistory]

For some context I live in Ontario Canada.

If I had a DNR and then attempted and doctors ignored the DNR could I still sue them or are they allowed to ignore a DNR in the case of suicide? I know DNR's are generally always followed but I've also seen people make arguments that if you're unstable enough to commit suicide you're too unstable to make the decision for a DNR. I can't find anything online that clearly outlines laws about this though. Does anyone have any idea how this would work?
