"The letter also warns that "should another report of this nature be received, then MCFD may be more intrusive and will be looking at both parents' ability to keep the children safe."

You don't find this at all chilling? What's to stop a malicious actor from making a bogus anonymous claim, especially during acrimonious divorces? It seems like an all too easy weapon to use against someone, where with nothing more than a rumour the government has the right to dig into all aspects of you and your children's lives, look at every intimate detail and decide your fitness, or worse, the fate of your children. It's especially galling that they admit he's done nothing wrong, but still put on notice to watch himself or else. Bureaucrats should not have this authority on mere hearsay, alone.
