From the HC FAQ on ephedrine and the availability of products:

6. Will all products labeled to contain Ephedra/ephedrine be taken off the shelves?
No. Commercial Ephedra/ephedrine products being sold as nasal decongestants and having a dose equal to or under the recommended dosage of 8mg/a dose or 32mg/day will continue to be available. Products containing Ephedra which are marketed for traditional use according to the combinations and dosages described in texts pertaining to traditional medicine, will also continue to be available, provided they do not contain caffeine and that the ephedrine content does not exceed the 8 mg/a dose to a maximum of 32 mg/day.

As well, the recall does not affect Ephedra/ephedrine products that are being dispensed by practitioners who are dispensing/compounding the drug for individual patients.

In other words...no ECA stacks...Here is the entire FAQ
