The CSA equivalent of IEC 1010-1 is CSA C22.2 No. 1010.1.  The National 
Forward states that CSA C22.2 No. 0 also applies.  This standard specifies in 
4.6.1 that 'Terminals that are intended for direct connection to either a 
grounded conductor or a neutral conductor of a supply circuit shall be 
identified unless their intended use is clearly evident.  They shall be 
substantially white in colour if colour coded, or be marked "N", "Neutral", 
"W", or "White" either on or adjacent to the terminal.'
     
I have had a CSA engineer in the last month inform me that 120 v circuits 
must specify "N" or "Neutral" or "NEUT" and that 240 V circuits must not use 
this term.
