Surely it cannot be too much sun, spring has just sprung and you are in Canada.

Maybe! I forgot to say that one of the leaves is also curled quite a bit

The leaves will bend to the light, so i always put mine back pointing the same way towards the window after taking them to the sink for watering.
How far away from the light source is the Phal? What sort of temperatures and humidity do you have?

Current readings next to the Phals on a cold miserable day outside are Temp. 24.6C Humidity 62%.
