The official date of compliance will be with Proclamation....at least with regards to ratios. I got a letter from the Ministry stating that. Proclamation is projected to occur no sooner than the fall...but we really don't know exactly when that will be. Yes, providers have had the Ministry show up at the door. I've heard of a few. One woman had a lengthy thread about this on FB just a couple of weeks ago. It is happening. I've not had it happen to me yet, but am getting my waiver done, just in case. The officials who showed up at this woman's door didn't say specifically what alerted them to her home. They indicated that it could be because someone lodged a complaint or there was an inquiry.
