It depends what the problem is you are trying to fix and how AHS is designed.
To fix a single point of failure is to determine if a backup is cost effective and just exactly what level of service is you can live with at minimum for a certain amount of time.
Example, if AHS uses a shaw connection to their contractors (IBM, which sounds is the major culperate here, not AHS directly but IBM acting as a contractor for AHS) then you install a second Telus/Enmax Envision line and you use both lines in //, example foothills hospital has a 10mbps line from shaw and a 10mbps line from Enmax giving them 20mbps at peak and 10mbps at times of issue and the network engineers can setup traffic filtering to limit bandwidth to only essential traffic (but this should all be in an emergency response plan).
If you want to fix IBM going down as your single point of failure, that requires likely a data routing redundancy that if AHS is one unit is likely cost effective by having a data centre in Calgary and Edmonton, if its just AHS acting for Calgary health region its likely not as cost effective. Again it all depends how AHS is designed, if Foothills had to cancel surgeries etc that seems fairly major problem either via network planning or emergency planning (are there no paper copies of work orders, is everything computerized).
911 Shaw telco customers, cant really fix that, phone numbers always will have a single point of failure - the phone itself. If 911 is extremely important for you so much so you are willing to pay more, Telus basic phone will always be a better option for 911 service than Shaw phone will be - you can use Telus when the power goes out but you cant use Shaw.
I personally think Shaw will be losing at least 1/3 of their dual service corp clients biz for those especially who have data and voip through them. Its not Shaw's fault per say but its simply prudent planning to have one company run one system and another run one so if you lose phone (voip) you at least have internet (email). The suits who have 2 letter designations for titles normally dont care about that until a pie lands smack in their face. The only good thing is it happened durring stampede so actual business disruption to the decision makers was likely limited.
I know of at least 3 mid companies(500-1k users) who where completely dead on everything but internal calling.
