The part before the clock starts
Canada reads official files in English, so any sheet in another language needs an English one beside it. Almost everyone counts the days from the moment they place an order. In practice the longest stretch sits before that, while the right piece of paper is still being tracked down.
If the record was made in this city, Nottingham Register Office issues certified copies of births, marriages and deaths from The Council House, Old Market Square, Nottingham NG1 2DT. That office works to its own timetable. Order the copy first, then book a certified translation into English in Nottingham, and the two waits stop stacking up.
Where the days actually go
Standard turnaround is 2–3 business days and very little of that is typing. Most of it is the second read: names, dates, numbers and body names checked against the source sheet, one line at a time. That pass is what a receiving desk in Canada is paying attention to, and it is the pass that cannot be hurried without cost.
The express lane closes in 24 hours. It works by moving your file up the queue, not by dropping the second read. Because there is no slack in it, an express job is the one most easily derailed by a dark scan, so send full colour sheets with the edges showing.
Planning backwards from the date
Start from the day the file is due in Canada and count back. Allow the run itself, a day for you to read the draft names and dates, and whatever the source copy takes to arrive. An official English translation in Nottingham costs about £25 for each page of source paper, so the budget is settled as soon as you know the sheet count.
One last habit saves more time than any lane upgrade. Send every page of a record together, in one go, in colour. Half the delays on a certified translation for Canada are not slow work at all — they are a file that had to stop and wait for a page somebody forgot to scan.
