Having similar dates...applied in April. Have seen a couple of other folks in the forum with these dates. Don't know if they got the PCC. Problem not only with May applications , but end of April as well.
I setup the appointment by calling BLS. Luckily they answered that day. Postal order from Canada post will work. No need to go to bank if it's far. You can schedule pickup/drop of package by Purolator, on the BLS website.
The Purolator tracker says the documents reached BLS on April 29th, but the BLS tracker says "No records found". BLS phone lines not responding. Is anybody here facing similar problem?
