Setting project to Wikimedia-Site-requests, as this request is about settings / configuration of a Wikimedia website.
For more information about how to request these kinds of changes, please see https://meta.wikimedia.org/wiki/Requesting_wiki_configuration_changes
According to my knowledge from Wikimedia Czech Republic (which is "my" chapter), you are free to have either black or "old" colored logo, provided you are officially recognized chapter (and you certainly are) and it is up to the chapter to decide. I don't know if I should take this as an official request coming from Wikimedia Canada. If so, please tell me, I'm going to proceed it.
Regarding your question, no, I cannot tell we're receiving "a lot of requests" to change a logo.
