No, you do not need to apply to IFHP, this letter confirms you are eligible for it.
Now you can go to a panel physician and get your immigration medical exam conducted without any costs.
It will be some time until you recieve a another letter or notice from the ircc (in my case it was after 1.5 months) to submit your biometrics and passport. After which you shall wait more to be called back for an eligibility interview which confirms if they'll grant you a refugee claimant protection document
