There are only 5 sites with campground facilities Comox BC; Greenwood NS; Halifax NS; Northbay ONT; and Petawawa ONT. I've been to the 2 NS sites, they are not like a KOA or any other commercial, National, or Provincial campsite. Much more basic, but clean and neat. Secure and safe. Their located in rural area's, so some driving involved if your aiming at "Tourist Attractions".
Note: I'm referring to the RV facilities, the cabins etc are very nice.
We do NOT have the wonderful selection available to current/former service personnel in the USA, you guys have your "act together" :)
Cheers.
