Hmm, this is what the letter i got says.
Some of the requirements for Canadian citizenship changed. These new changes provide more flexibility for applicants in
meeting citizenship requirements and as your application was
received at the Case Processing Centre in Sydney, NS
on or after
that date, it will be assessed based on the new requirements of the Citizenship Act. To learn more about the new citizenship
eligibility requirements, please visit our website at
www.cic.gc.ca.
It did not say exactly what day is "that date", but I assume it is Oct 11th.
