Residential fire sprinklers.

[Tod]

Hi All
Does  anyone know who would be licensed to install fire sprinklers in 'one to two' family residential dwellings? Is there a code? We have plumbing and hvac licensing and have suddenly been asked twice so far in 2019 about carrying out the work. We have asked colleagues if they have any experience in this line of work and have so far drawn a blank.
Any feedback would be appreciated.

In Ontario you need to hold a 427A Certificate of Qualification with the Ontario College of Trades.
