Open Note to Canada Post

I plan to mail some stuff. So, apparently the stamps I want to use up need glue. So that's one more thing to get tomorrow along with no-scent soap, toothpaste, compression socks (that have been discontinued by the manufacturer in my size and pressure-rating but there's still two pair within public transit shopping range), and assorted groceries.

Also, seeing as I have these odd denominations of stamps - 65¢, 93¢, $1.10, $1.20, a few others - that are just peel-and-plant-on-envelope, I'd like to see the smaller denominations similarly formatted for sale wherever possible. From 1¢ on upward to 50¢, please?

And if such is already offered via their online catalogue, can anyone advise me where to look for them?
