Canadian services are typically good especially for urgent care things, I only have gone private on one occasion and that was for an MRI years ago when there were fewer of them available. I had a tear in my MCL and they wanted to see the degree (relatively low priority, it wasn't a full tear and I didnt need surgery). The wait for the MRI was ~6 weeks but so just paid out of pocket privately and had the results sent to my doctor. Took 2 days and he got what he needed.
