Lots! You wouldn't necessarily guess we are Canadian by just walking in the door, but we have bed pillows from Super Store with maple leaves, Canada Day party supplies (paper plates, table cloths, centerpieces), books on Canada, which I'm sure have a maple leaf on them somewhere, clothing, lapel pins, temporary tattoos, flags, mugs, Beanie Babies, food packaging,...I'm sure there is more. I used to have a maple leaf soap dish and maple leaf soaps for "decorative purposes" in my bathroom. I do a lot of jigsaw puzzles and I specifically pick up ones that are Canadian inspired themes, which definitely have maple leaves on them. While not a maple leaf, I do select (when possible) red kitchen tools or other items. Again, this is not SO OVERWHELMING that anybody would really notice, but in my head, I know why certain items were chosen.
I have a D & D character who wears a bright red cloak and uses maple syrup in her magic and maple leaves are symbolic to her.
My Disboards avatar is a maple leaf, so every time I am on the Disboards, I have at least two maple leaves in my house as well.
Would I have had all of this stuff if I had remained in Canada and not lived in the US? Not as likely.
Mike Meyers once said, “There is no one more Canadian than a Canadian who no longer lives in Canada” That definitely describes me. I am the annoying person who points out Canadian artists when they come on the radio, or if someone says they like something we have, I will say, "Thanks! We picked that up in Canada!"
When we eventually move back home, I'm going to require therapy to tone my enthusiasm back a bit.
ETA: Our passports and some Canadian money also have maple leaves and I forgot about two Roots pencil cases.
