Canada has had braille dots on its notes.  In late 2011 Canadian notes 
switch from cotton/paper to plastic which makes braille dots easy and 
durable.  Each denomination of note is also a different colourCanadian 
coins are the same denominations as US coins and are mostly the same 
size.  In Canada the five cent piece was likely called a nickel because 
when the original silver 5 cent piece, that was smaller than a dime, was 
replaced by a larger coin of base metal, it was nearly pure nickel.  
Canada also has a 50 cent piece, but like the US they are not circulated 
much.  The last time I relieved one in change was 40 years ago when 
crossing the international bridge at Cornwall ON. the toll was an even 
half dollar increment so when you got change for the toll gates they 
gave you 50 cent pieces.  I still have one or two of them.
