How is your riding style? Do you use mainly the throttle? Granted I have very little experience with an e-bike but I assume it will take a lot of effort to burn up a motor.
I may be misreading it but you said you hired a professional to install the upgrade. Therefore when they were done I assumed everything worked fine.
Now that I have a few kms riding my City+, I can comment regarding the hills of Burnaby. I grew up near the Royal Oak hills. And I used to work near BCIT on Canada Way. I have ridden my bicycle on those hills a lot. I now lives in Calgary and have ridden hills comparable to Burnaby and I must say that they are doable with the combination of PAS and the right gearing. I do not mean to compare myself to you but I said it to help understand where the problem is. There is a big area to troubleshoot between the battery and motor.
