I'm sorry I'm not familiar with your area, so I can't provide a specific studio name... but for my husband and I, we printed off the specifications for Canadian passport photos and brought them with us to the photo studio and asked if they could meet these specifications.
The studio that did it for us said they could, although I measured the pictures after and they were 1 mm too narrow on the width but perfect on all other specifications. We did not have time to re-do the pictures and sent them in anyways. So far our application has successfully gone through the initial stages of processing without problems (SA, meds passed, biometrics passed) despite the slight discrepancy in photo dimensions.
All that to say, if you bring the Canadian passport photo specifications with you and show the studio, they should be able to determine whether they can do it for you or not. If need be, you could also call ahead to nearby photo studios and state those dimensions to them and see if they are okay with doing it.
Hope you find a good photo studio!
