In my home province of Manitoba whenever someone is going to get married, the couple has what is called a "social".... Not a super-weird or exciting custom, but I'm told it's unique to our province.
It's not. Most provinces in Canada have "Stag & Doe" dances to raise funds. Often it's organized by the best man and maid of honour; at other times it is the husband's family, to offset the cost that the bride's family will pay at the actual wedding.

I like customs around death, including:
-leaving food / money out for the grim reaper to avoid them killing a loved one
-not mentioning a dead person's name until after the funeral
-taking the shows off a corpse so the restless soul can't get back home to haunt the living. (this is from certain north american native tribes I believe)
-burying is outlawed, so bodies are placed in a magical masoleum where people can pay a fee to talk to the departed ones
-not only covering mirrors but doors and windows in black silk after a person died
-the dead can only be buried naked
-white, not black, is the colour of mourning. I believe this is ancient Japanese custom
-all of the funeral mourners must stab the victim with a ceremonical dagger, as a ritual death killing that they control
-the spirit of the decesed shows up to the funeral. They say nothing, but they hear all of the words spoken to them. It is believed if you say bad things about them, they may end up haunting you
