Basement flooding from rain and snowmelt, looking for advice on cleanup in Calgary

With all the recent rain and snowmelt in Calgary, our basement flooded and caused some water damage. This is our first time dealing with something like this, and it escalated faster than we expected.

For people in Calgary who’ve gone through flood cleanup, what steps made the biggest difference early on? Are there things you’d recommend doing (or avoid doing) right away?

Thanks in advance for any tips, especially local resources or services that helped you recover.
