Getting out is not the hard part. It is getting in and going again without getting wet.
To get out:
If the beach is large enough come in sideways, lean away from shore to as you beach. when the canoe touches bottom on the shore. sit upright and you should be well grounded and close enough to step from canoe to shore while staying dry.
If the landing is narrow, move people as far back as practical, beach the front (bow) and then walk to the front to get out. If two people, the one in the back stabilizes while the one in front gets out. then the when out the front person drags the front of the canoe farther on shore.
To get in reverse above, but as you are moving from stable shore to rocking boat, it takes a bit more practice.
You might want to go to a local lake and practice before your trip. Bring a change of clothes, just in case. This skill is best learned where getting wet and cold is not going to have a huge impact on the rest of your day or trip.
Additionally, roll up your pant legs before getting in or out, to keep them dry. Your bare leg dries faster then your pants. I usually wear water shoes that dry quickly if they do get wet rather then trying to wear heavy boots that will stay dry. Remember you may be swimming in whatever clothes and shoes you are wearing, so plan for both events.
I keep a change of shoes and socks (& clothes & towel) in my dry storage, in the canoe. In the event that I need to walk out (and/or for camp) I have dry shoes and socks appropriate for land, that will be dry even if the canoe is capsized.
