Issue dates are subject to change by Canada Post. These are envelopes with a special cachet and cancel commemorating an event. They are not a new stamp issue but are an official Canada Post Product. These sell for $3 each (unless otherwise indicated).
Starting May 31, 2015, rate for 1 ounce First-Class letter (or postcard) to Canada increase from $1.15 to $1.20. See the links below or Page on stamps.com. I can't keep up with the changes, so I always look up the rate for postage whenever I send a letter or package when I'm about to send it.
