Caution - I haven't used any of these. My first OTTB was bought from my old coach who found her in Michigan, and my second was brought home right off the track by my friend who works there.
If she doesn't need something with any retraining she could go straight to the track, or I could pass along her wish list to my friend. She rehomes quite a lot of OTTBs and OTSTBs every year. We're in southern Ontario.
I've spent most of my life riding horses. The rest I've just wasted.
My DIL lives in Montreal and she bought a nice mare through Second Start. The mare was in Fort Erie and my DIL lives in Montreal. Shipping was only $500! She got the mare on one of the transports that goes to the Maritimes.
The mare was doing well, jumping, etc. Then my DIL got pregnant and the mare did hurt a suspensory in January. They are now both starting all over again. She did not see the mare before purchase and she was quite skinny when she arrived! https://www.facebook.com/pages/%C6%B...143164?fref=ts
I know a couple people who have adopted from Adena Springs and they are very happy with their horses. One is an eventer and the other is doing hunters. They do a good job restarting the horses once they come off the track.
I'll put in a third plug for Longrun. I'm a little biased, though - I've ridden several cool ponies from the program, and I have one friend that works in the office and another who fosters for them! Check out their Facebook page here - https://www.facebook.com/LongRunTB?ref=ts&fref=ts
