Usually any construction done using the code in effect at that time is considered "grandfathered".
However there may be exceptions other considerations that may apply IE :accident volume etc,

The rise 7 7/8 has pretty much stayed the same and has not been a matter of controversy. however the width of the
tread has been increased and seems to have been the main cause for concern.
Expert:  Machinc replied 1 year ago.
I will be glad to answer any questions you may have.
Expert:  Machinc replied 1 year ago.
There were no changes for private stairs in the 2010 code.
It was the same as the 2006 code
Expert:  Machinc replied 1 year ago.
The 2010 code did increase the tread to 280 mm for public stairs
The riser stayed the same.
Expert:  Machinc replied 1 year ago.
NOTE : some provinces have their own code or have not adopted
The Canadian Code . It would be advisable to check with the permits and
inspection department of your local area to be sure that compliance has been met.
