Brave’s Tor mode, introduced in 2018, was sending requests for .onion domains to DNS resolvers, rather than private Tor nodes. A DNS resolver is a server that converts domain names into IP addresses. This means the .onion sites people searched for, with the understanding those searches would be private, were not. In fact, they could be observed by centralized internet service providers (ISPs).

It doesn't seem to be the case that anything with javascript must leak canvas fingerprints.
Are you saying that Brave is unsafe because it has JS like every other browser on the planet or because it doesn't resist canvas fingerprinting specifically?
