Hmm, I'm definitely sensing a bit of an attitude in you today.
Well, that's a bit tricky considering you exist in the 19th century and I exist in the 21st century. But let's see what I can tell you about the mail service - maybe someone who works in it knows of a way to send mail to the future.
It was actually in August, 1527, when the very first known letter was sent from Canada - from St. John's, Newfoundland, when John Rut wrote a letter about his upcoming voyage. It was sent overseas by ship to England, addressed to King Henry VIII. Mail delivery within Canada, though, started in 1693 when letters were delivered between Quebec City and Montreal.
In 1867, the year you live in and the time of Confederation, Royal Mail Canada comes into effect. The post offices are placed under the post-master general of Canada, who is a member of the Canadian government.
I would love for you to send me a Christmas card, Abby. Please send it to me in care of the 21st century.
And now you know.
