Also Canada, my optometrist has never given me a problem asking for my prescription. However, they don't measure the Pupil Distance (PD) which your lens fitters might require.
This measurement is the distance between your pupils in millimetres. It can be measured with a standard ruler. Mine is 69 (nice)
My optometrist explicitly does not measure the PD because the glasses shop they have adjoining doors with will do it for you. We often just measure ours at home because it's far cheaper to shop for glasses online.
Awesome. I have the PD measurement from that picture, along with other measurements.
I assume this covers everything the lens folks will need.
Your PD is here so that's fine. If however you require a multifocal/progressive or computer/office lens you will need heights. The heights in this picture are only applicable to the frame you are wearing. However if you're going to another dispenser to buy frames and lenses from them they will measure you up.
For the record, in Australia your lens prescription is your property, but as was stated by someone else usually the optical dispensers will take your PD, and they often aren't recorded on your script. Also, as a dispenser if I call your optom to request a copy of your script, they will give me the prescription but not the PD. It's something usually taken w, at point of sale.

Thank you kindly for the reply. This makes some sense. It is just so scummy feeling because the information is there, it is about me, but I can't use it to shop around. I probably just had a great opto who went above and beyond back in the day and that coloured my expectations.
Yeah, we deal with some practices that don't easily share prescriptions. There's always bad eggs! If a customer asked for their PD I'd give it to them, but conversely if a customer came to me wanting lenses and told me their PD I'd measure it anyways. It's really only important for you to know if you're ordering lenses online.
