Kamala maybe, but no plurals for me - I experimented with a few very popular female first-names + S that seemed to have a lot of use, but none sold and there was absolutely no interest at all with outbound. Fool's Gold.
Canada has a small population, so use the 10% rule to your advantage.
When it comes to First Names, here are my personal guidelines, 1) only register popular first-names, 2) stick to singular names, and 3) female names are far superior to male names.
Remember that in this market, you are mostly going for a professional who depends on their name value for publicity and advertising (i.e a realtor), who may want to own their first name for a personal-business website.
