Leader: Justin Trudeau
LUA: Sunny Ways - Player receives two copies of the Cannabis luxury resource that can be traded (but must keep one copy at all times) and provides +6 amenities to all cities

UA (regardless of leader): Peacekeeper (same as smartcanuck1988's suggested UA)
UU (regardless of leader): Mountie - Replaces Cavalry (+5 combat strength and provides +1 amenity to a city that the Mountie garrisons (stacks with the Retainers civic card))
