Canada (pronouced /ˈkænədə/) is a country occupying most of northern North America, extending from the Atlantic Ocean in the east to the Pacific Ocean in the west and northward into the Arctic Ocean. It is the world's second largest country by total area. Canada's common border with the United States to the south and northwest is the longest in the world.

Contacting OSM Canada
There is a mailing list set up for Canadian mappers. Most discussion about country-wide matters takes place there. Both official languages are welcome. Join the list here.
There is also a chat room for Canadian mappers on OFTC's IRC network: irc://irc.oftc.net/#osm-ca. For more international discussions related to general mapping (in English only); you probably also want to join the main OSM channel at irc://irc.oftc.net/#osm.
There is also a OpenStreetMap Canada Facebook page Please make sure everyone who indicates that they are a 'fan' to become an admin to the page, this way, all content of the page can be edited by everyone. (Just like OSM & the wiki)
There is also a website that includes a task manager for mapping in Canada
GPS tracks perhaps the best way to collect data. When you go out on trips, take along your GPS device and upload your traces to OSM. Be sure that your GPS device is set not to lock traces to the copyrighted data stored in the device; the purpose of collecting traces is to create new, unencumbered data. Photo mapping is an efficient way to create detailed maps.
Mapping parties are a great way to kick off mapping efforts in a sparsely-mapped area. By contacting other local area mappers, you can arrange to meet in a place that is convenient for everyone. When you meet with other mappers you can then learn first-hand the other techniques that are available, as with OSM, the possibilities are limited only by your imagination.
For those without a GPS, fieldpapers.org allows you to draw directly on a printed OSM map, scan it, and trace from it using an OSM editor.

Importing government data
Since 2008, the federal government has released a wealth of geodata for use in OSM. The OSM community is at work completing the existing OSM content with the government data.
Initial efforts were based on simple feature data from GeoBase, which includes administrative boundaries, place names, roads, and bodies of water. This import was mostly done wholesale in areas with little previous OSM data. Before street names were added into the GeoBase data, street names from Statistics Canada were imported; this resulted in many incorrect street names because of the differing geometry between the two datasets.
Currently, the data source of choice for importing is CanVec from Natural Resources Canada, containing most of the GeoBase data, plus extras such as important buildings. NRCan is generating an OSM XML version of the CanVec 6.0 dataset, and the most populous areas are now available. These files can be imported using offline editors such as JOSM. Please only import areas and features you are familiar with. If you have any questions about how to import the data, ask on the list or channel.
Here are some other government sources that may contain additional data.
Toporama, a WMS service serving rasterized CanVec data, can be used as a background layer in OSM editors. To use it in JOSM's WMS plugin, use these links:  (more detailed), or  (less detailed). The GeoBase NHN WMS at  provides more detail for water features, such as water flow direction and water junctions.NRCan PDF sheets PicLayer or Map Warper.
Statistics Canada data is used to import street names where they are missing from the other data sets. It is advised to not copy the geometry; however, you can use the street names database as a reference.
Ibycus Topo is a Garmin map compiled directly from source CanVec data (shp files) as well as GeoBase data (shp files). This is a free (dont sell) non-routable map which also includes great contours from CanVec. (contours are not included in OSM, so GroundTruth Planet Contour is used instead). This can be used as a supplement when using OSM Maps as an overlay. NOTE: The .typ file (tags) which was used for conversion is slightly different than the tags used in the OSM version. However, as this import process will take some time, end-users are welcome to use both maps for navigating, and users can 'pretend' that the CanVec data is already in OSM, while finding new features to add to OSM.

Open Data - many municipalities have Open Data datasets suitable for importing now, this is a list of them
If you have a goal that you are working towards or one that you would like to see get done (and are maybe willing to get the ball rolling) then add it to the list here, create a section where it can be coordinated and tracked, and a way of measuring progress.
Crowdsourcing buildings with Statistics Canada
Statistics Canada initiated a pilot project aimed at understanding the potential of data crowdsourcing for statistical purposes.
The project is making use of OpenStreetMap as a platform for inviting contributors to crowdsource information on buildings (footprints, addresses and simple building attributes). The pilot project will focus on the Ottawa-Gatineau region for now.
Currently, there are no accurate statistics on buildings and their attributes at the national level for comparison of specific locales. The information you submit will help to fill existing data gaps and provide new analytical opportunities that are important to data users. As well, the project will teach us about the possibilities and limitations of crowdsourcing. This may be a new way for Statistics Canada and other organizations around the world to collect much-needed information by working with contributors.
We are looking for any useful information for buildings but more specifically:
- Type of building (main Building tag)
- Full address (Address field)
- Reduced mobility access (wheelchair access)
2. Activity (office tag for none commercial specific activities, this is for type of offices)
- Shops and amenities (points)
Custom Garmin maps
- Create a Garmin MapSource install file for Canada and/or provinces
- Create a combined transparent routable OSM/topo map for all of Canada using Groundtruth SRTM data and, the most current OpenStreetMap data. So that it can be installed to Garmin MapSource & Garmin IMG tiles for use to install onto your GPS device.
- The contour-only maps are currently (Feb 5th 2010) being generated, the files are being made available in the mediafire.com folder SRTM_GroundTruth_Canada These are all 10m contours, and about 100 megs each .zip file, and covering approximatly 2x2.5 NTS tiles (5 tiles at a OSM zoom level of 8. For example On OSM the box & the surrounding area.
The Garmin MapSource (Windows) Installer file for each province is available here http://www.mediafire.com/?sharekey=3b30da6df5072902ab1eab3e9fa335caa2ed10992d240aa5
created from the OSM download of the outline of each province from http://downloads.cloudmade.com/north_america/canada .shp files are also available as well as pre-made .img tiles that you can install directly onto the device\
Trans Canada Trail
Status: Please note the copyright restriction. ALL trails must be actually navigated with GPS and/or imported from one of the data sources that have the same compatible license as OpenStreetMap. See Canada Import Status. These trail segments are mainly mapped as a national trail network - network=ncn, only if the trail is usable by a bicycle end-to-end (see Cycle routes). Otherwise, the trail segments should be mapped as regular trails.

Canadian best practices
Canada has a wide range of data that can be imported. So if you are local and on the ground the best place to start is checking the interfaces between the imported data and the data that was in place before. Typically you'll find that imported CanVec data has been truncated at the interface with original OSM data so make sure that the roads that should be joined are. You may find roads traced in from satellite images are not quite in the right place. GPS traces can help here.
When you browse the slippy map on openstreetmap.org, note the + sign to the right. Zoom in first then click on it, and tick the data box. Note the Points of Interest (POI) that show on the left. Click on one these and you'll see the tag values for the POI including things like website that are in the database. This means tags such as phone=*, website=* etc are worth entering even though they don't immediately show on the map but are accessible if you want to order a take away. Note the warning that comes up about the number of POIs and the amount of data that must be transferred. Ideally we do not want to store redundant data so for an address we want addr:housenumber=*, addr:street=*, and addr:postcode=*. Cities typically are marked in OSM as a place and a boundary relation and anything in the city's boundary is assumed to be in the city. So when we search, we take the city information from the objects describing the city itself. Provinces and country are the same. Address interpolation is a useful way of keeping the number of POIs down but still allowing a search by house number.
|The following paragraph may contradict consensus established on the mailing list; please discuss and try to rectify this.|
OSM has different methods of rendering. Some of these rendering systems can make use of French as well as English names. For bilingual areas such as Ottawa the convention is to enter the English name under name, and the French name under name:fr. Example name "Wilkie Drive" name:fr "promenade Wilkie". Renderers such as Maperitive can be set to display the French names as default.
Note also that most rendering systems will not show all the POIs on the map. The ones that are omitted can be shown by the use of "rules" but this is currently a little more complicated than casual users might like.
OSM is an electronic database that is converted or rendered into a visible map by programs. Programs are dumb but very fast. They work best with consistent tags so follow the Canadian tagging guidelines and the Map Features. For example cycle lanes should be labeled cycleway=lane to show up on + "Cycle Map". There are now some applications that work with the POIs, such as MapOSMatic, but in order to find the right ones the tags must be consistent. There are bots that are run on the data cleaning it up so it is not necessary to clean up existing tags, leave it to the bots.
Please add value by adding footpaths, specialist stores, playgrounds and parks. These are often missing from other maps.
What's with the forests in Canada?
The squared off sections of forest in Canada are the result of the ongoing CanVec data import. CanVec tiles were broken up into squares called the NTS grid to better manage the data import. If you see a forest that's squared off with a empty section beside it, it's most likely that that grid has not been imported yet.
