Plan price changed

I was on a $35 a month for 50gb. The plan increased to $40 a month without any notification, has this happened to anyone else?

Edit: I've seen many others post that their bill also increased $5. For now, I moved to a plan within Koodo for $40 a month for 65gb. Save an additional $5/month when you use auto pay, while I wait for black Friday deals.

My only other dilemma is I use Stream+ which is a solid deal for Netflix, Disney and Amazon, not sure what I would do about those if I decided to move providers.
