Thanks for the context on this; I took this and the dentist note as I had spotted them through the bus window and was planning on keeping an eye out for them on the next ride.

The answer to your question is not what I expected - this building contains both addresses and has an entrance with steps facing both East Lake Avenue and York Road. I had been seeing the dentists' sign for years but had never noticed the cannabis one before. The building was used by a different dentists' practice that has left and is now operated by a doctor who is both a dentist and a medical cannabis provider.

The way I will tag this is as a healthcare building with two address points in it, and two separate points for the two businesses since they are operated separately.
