There are currently no licencing requirements or permits required to operate as an inspector in Ontario. Currently the major association in Ontario is going through some difficult times, and that leaves Nachi which is unorganized, and ASHI which is an affiliate of OAHI - Ontario Association of Home Inspectors. Even though I have been a member of all the Associations, and currently a member of OAHI I have realized that the associations have done nothing for my business since 1991, and I have yet to receive any referrals from them. My work is coming as a result of reputation and length of time in business. I can give you a run down on them all if you wish to call me at 519-942-9496. Cheers, Raymond Wand
