The Atlas of Canada's interactive topographic maps are designed to be easy to use, but you may not be familiar will all the features and tools.
This Help document describes the interactive features and explains how to use them.
These topographic maps mainly show data from the 1:250 000 and 1:50 000 National Topographic Databases and are seamlessly linked together. They originally come from over 13 000 individual maps. The currency of the information, from these source maps, varies so not all features shown will be up-to-date. Liability restrictions apply, so please read the liability note regarding geographic data from these topographic maps.
The maps also show data from the Atlas of Canada’s Framework datasets at scales of 1:30 000 000, 1:7 500 000 and 1:1 000 000.
The roads are from the GeoBase Portal, a new federal, provincial and territorial government initiative. In addition the satellite image, CanImage, and elevation image, Canadian Digital Elevation Data, are also offered. If you would like more specific information about the currency or other details of any of this data, please go the Map Sources section.
If you would like more specific information about currency or other details of any of this data, please go the Map Sources page.
For answers to many common questions about these topographic maps, visit the Toporama Frequently Asked Questions page.

The 1:250 000 and 1:50 000 Map Sheet Index layers can also be turned on and viewed over top of the map by clicking the box to the left of either layer name. These layers are helpful to find the actual National Topographic System map sheet number. You can use this number to purchase a printed map, the data used to produce the map, or find information related to the currency of the map and data.
The next entries in the legend are groups of specific types of topographic information such, as roads. These groups are always visible except when the satellite and elevation image layers have been turned on. If you wish to view any of these groups on top of the satellite or elevation image layers, click the box to the left of any of the group names.
