Room is a Canadian literary journal by women and about women. They are currently taking submissions for their latest issue: Canadian Gothic. Their submissions deadline is January 31st. Click here to read the submission guidelines for this issue.
I have been in contact with Room and while they have only accepted short stories, poems, creative non-fiction, or art in the past, they are now accepting comics as part of the submissions. They are not limiting the number of pages for the comics, but the maximum word count is 3500 words (if there are words). I don’t know what their requirements for page sizes are, so I recommend you contact them to find out more details.
