Wanted: Looking for horse back riding lessons on gaited breed or part B

Hello, I was hoping for lessons or part board on an Icelandic or other gaited breed. I seem to do best on gaited breeds. I have ridden horses all my life but took a very long break and am not nearly as good as a rider as I was as a kid. I live in Brampton Bramlea. I was part-boarding a rocky mountain horse for a while a few years ago but she was not fully trained. I am looking for a horse to take out to the trails maybe one day long long-distance endurance ride. A -trained horse that is sure-footed and confidant is a must. I have also ridden many saddlebreds and loved them as well. Most of the horses I ride are very speedy but will slow down. Some of the more untrained ones would only go faster and faster lol I am trying to avoid horses that do that and stick to ones that will slow down even if it is if they slow down slowly. I do not mind fast horses who love to go as long as they don't take off in a gallop and go faster and faster. Send me a message if you know of any. Ty so much.
