I found this article interesting. Essentially because the Canadian show scene here on the west coast is absolutely fantastic. The H/J barn I rode at for many, many years has bought the majority of their horses out of Canada. As a matter of fact, our retired mare was bred in Canada (by stallion Glencoe), and purchased from Milner Downs. As was probably half the horses in our barn at that time. The quality was amazing in the BC area, and still is.
I don’t know about other parts of the country, but the show scene in BC is as good as anywhere. The top Canadian trainers on the West coast win up and down the coast from Thermal, CA to Langley, BC. They’ve produced several Medal Final winners, and lovely hunters. ‘Overdressed’ comes immediately to mind.
As for drugging - I’ve seen enough to know it happens, and has been back going on through the decades. From the era of OTTBs and tranquilizers, to today, where the slow off the ground, and the slow, big jump is required for weeks on end. It’s not new. It’s been going on forever. And it’s certainly not just the US. Canada is as guilty as anyone else when they show in the US. And, of course, it isn’t everyone. However, it’s hard to prove, but most people aren’t stupid. And if you keep your eyes open, it’s pretty clear which barn’s have horses with a shelf-life, and which don’t.
I don’t know about other parts of the country, but here, the quality of the Canadians are incredible, and more than equal to the US.
