Move to Canada?
I'm not having any problem with finding shoe polish here, and all the colours are available. Have you tried a tack store or as suggested a place that has leather boots, like cowboy boots or work boots.
The tack store will have all the leather care items for sure, and any place that sells cowboy boots will have all the polish colours. Work boot places will probably only have black polish but they should have the mink oil or other such product to go with it.
