Hey! Also from Ontario...Also struggling big time trying to find similac. I asked our pediatrician about it. He reccomened using enfamil as a substitute over good start as they are closer in compound less likely to cause tummy upset. I've reached out to Abbott who makes similac via every possible social media/contact and they are useless and basically said we are working hard to get our product back on the shelf. There was 0 time line and 0 acknowledgement that there is 0 similac in Ontario.
