Yes. Banking information is not transferred from one insurer to another insurer for reasons of confidentiality, this is why if you want direct deposit you must enter your banking information in the Sun Life system.
You have the same coverage with SunLife as you had with Desjardins.
There are some enhancements. For example, the maximum lifetime coverage for travel was $1M and now is increased to a lifetime maximum of $3M.
In addition, at the pharmacist or dentist (if your dentist is set up for electronic submissions) you no longer have to pay the full amount and claim the refunded portion; you only have to pay the amount not covered under the plan
