How about just plain old DNSSEC?

DNSSEC and DNS-over-HTTPS/DNS-over-TLS are not the same thing and don't
protect against the same threats.
DNSSEC protects against DNS cache poisoning by verifying the digital
signature and therefore integrity of the zone's contents. That is, it
provides authentication not encryption.
DOH/DOT provides transport level encryption of the contents of the DNS
packets themselves from the host to it's resolver. This provides
protection against packet snooping on the wire, for example on an
unsecured WiFi connection.

I would love if Bell.ca offered DOH/DOT service on their
recursive/caching resolvers.

DNSSEC adoption is indeed a problem. IMHO, this is because it is a pain
to implement properly and provides little benefit to the user of the
zone in most cases. Improperly signing a zone will result in it not
resolving which is one hell of a failure mode for most people to put up
with. I only recently started signing my domains again and that is only
because my managed DNS provider made it very simple, as in I click a
button, zone is signed and I add the ZSK digest to my domain registrar.
