What else? What is your secret sauce in hiring and retaining talent?

Judith here with Clean Club Calgary.  We are a residential and commercial cleaning company.  We have been in business for over 15 years and we were able to grow to a 20-22 employee company.  I find hiring goes in spurts.  Sometimes we have great retention and get good hires through the door.  And of course there is the other times.  My target for employees is newcomers to Canada.  This is where I get the best people.  We do have a solid (not perfect) hiring process.  We are super transparent about the job (driving is part of the job, you might not get to work in the area you live, there will be changes to the schedule, we will support you - we have a supervisor on staff - and of course you are our number 1 customer - is the message they get) and even like this we have had such a hard time hiring.  We participate in job fairs. 

So my question is other than Indeed (which does work for us) and local Facebook groups, where do you go and recruit for your staff? How do you communicate the expectations of the job? How do you make sure that they are excited after their training period and happy to work?

Any help/advice/experience share is welcome!
