Google pixel 9 pro has 2 pink/purple pixel lines

When did you purchase the phone?  Did you purchase from Koodo?

Did a phone restart fix things?

On an OLED screen like the pixel pro 9, pink/purple pixel lines almost always indicate a “hardware failure” or physical damage to the display panels. Unless the phone was recently dropped or exposed to water, it is considered a manufacturing defect. 

You could try to rule out software glitch by restart the phone or check it in “safe mode” to see if the issue is still there.

If that issue persists, you will likely have to look into warranty/repair options. the cost will depend on when you bought the device and if you bought any extra insurance. 

That seems like a hardware problem.

I am not sure if this applies to you, but you may qualify for a free display replacement through Google’s Extended Repair Program. It should be available for up to 3 years from the original purchase date. https://www.androidauthority.com/google-pixel-9-pro-extended-repair-program-3623411
