Local optometrist will not provide PD measurement

I just had an eye exam done at the same optometrist office where I’ve been going 10+ years. I’ve always gotten my glasses from them, but due to a significant cost of new specialty lenses needed, I need to start ordering online. They refuse to give me my PD measurement.

Is there a place in Winnipeg that will do your PD measurement for a fee? I’ve tried apps and they are not consistent.

EDITED TO ADD: Thank you Winnipeg! I tried Zenni, Eye Measure, Glasseson, and Kits measurement tools and they were not consistent at all. I ended up going to an optician who measured my PD properly for a fee of $35. It was well worth it as I have 2 different readings for left and right which may be why the apps didn’t work as well for me. They have earned my business for all future eye exams.
