There is a lot of land north of 60. Without knowing more about where you desire to go it is difficult to offer much advice. If you might be interested in the Yukon, then Whitehorse fits the bill of being north of 60. There are two good outfitters in town, who will rent canoes provide guided trips, or provide advice on going it alone. I can recommend Kanoe People,
https://www.kanoepeople.com with their shop right on the bank of the river. KP has done well with me and my race team, providing space to work on configuring our canoe plus advice, tools, and parts.
Alternatively, Up North adventures is only a block away in town.
https://upnorthadventures.com I have not used Up North other than buying a few things from their shop, but I have heard they are very good as well.
