A Complete Guide to Waze in Canada
Welcome to Waze map editing in Canada and to the editing community!
Since the USA and Canada share the same Waze server, many of the policies and best practices that have been developed for the US also apply to Canada. This page contains information that is unique to Canada. Because some of it is still being developed, please follow the guidance for the US where it is not in conflict with the information here.
This page is now in development and will soon be available in French.
Please see the article Getting Started.
Another great resource for new map editors is the Welcome to WME.

Please check out the Canada-specific forums here: Canada Forum
Feel free to post questions and ask for advice in your editing. Our region is very different in a number of ways from the United States, so the generic editing guidelines don't always apply.
If you are an Area Manager that covers part of Canada, or a Country Manager that does a lot of work in Canada, please add yourself to this list. See comments via an "Edit" of this section to add yourself.

Area/Country Manager Requests
To request Area Manager or Country Manager access, please see this thread: AM/CM Application
Canada has its own forum area for unlock/update requests. Please make your requests here.
Please report future planned road closures via this form.
This form allows for complete (or directional, i.e. A->B only) closures to be reported. Partial closures (i.e. one of two lanes in a direction) should not be reported.
Major Events (e.g. Commonwealth Games, Tour d'Alberta, etc.) should still be dealt with using the Waze Major Traffic Events form.
This method is preferred over adding restrictions -- it is nearly immediate (processed several times per day by Waze staff), and does not rely on a tile rebuild. The closure will also be visible in the app and on the livemap, in addition to avoiding routing through the segment.
Map Editing in Quebec
Practical application in Waze: restrict all U-turns in Canada unless there is a sign outright permitting them. Unlike in the US, this rule also applies to parking lot aisles.
British Columbia Statute: Motor Vehicle Act of British Columbia
Alberta Guidelines: A Driver's Guide to Operation, Safety and Licensing: Cars and Light Trucks
Manitoba Statute: C.C.S.M. c. H60 The Highway Traffic Act: Section 191
Ontario Statute: R.S.O. 1990, c. H.8, s. 143. Highway Traffic Act
Quebec Statute: Highway Safety Code 
Newfoundland and Labrador Statute: RSNL1990 Chapter H-3: Highway Traffic Act, s116
To save space, only enter the name of the city. For example, "Toronto" not "City of Toronto", or for smaller places use "Springfield" not "Town of Springfield", "Village of Springfield", "Springville Township", "Regional Municipality of Springfield".
NEVER include the province in the City field. For example don't put in "Springfield, Qc" or "Springfield, On".
If you find a city that can't save without the province name (perhaps it changes when you save it, or generates other save error), please post a message in the applicable province's forum.
This applies to both primary names and alternate names -- the alternate city is assumed to be in the primary province and country.
Freeways, Minor, and Major Highways should be named in this format:
Nova Scotia, Ontario, Manitoba, Saskatchewan, Alberta,British Columbia & Territories
Hwy # (H is capitalized, the 'wy' in lower case, followed by a number) e.g. Hwy 16
Not 'Highway #' or 'HWY # (all caps)'.
Quebec, Newfoundland and Labrador, New Brunswick and PEI
Rte # (R is capitalized, the 'te' in lower case, followed by a number) e.g. Rte 16
Not 'Route #' or 'RTE # (all caps)'.
- For ALL of Canada
- Where the signage indicates the highway based on a name ("Lougheed Hwy" or "Sooke Rd"), the name should be used. If, however, the signage refers to it by number primarily, that is to be the primary name, regardless of the local knowledge (e.g. the Sea-to-Sky Highway is signed as Hwy 99 and Wheeler Blvd. is signed as Rte 15). If a numbered highway has local named signage as above e.g. "Lougheed Hwy" or "Sooke Rd", the Hwy number must be used as an alternative name.
Big Green Signs
- Segment naming for ramps and wayfinders should follow the Big Green Sign (BGS) text with the following rules.
- Segment name should generally follow signage as read, i.e. left to right, top to bottom, except all numbered highways, should be shown first, followed by destination, followed by icons if applicable. All should be separated by a forward slash (“ / “), with a space before and after the slash. Most BGS layout follows this standard.
- Acceptable icons to use are “✈️” for Airport and “⛴️” for Ferry. You must copy and paste these exact icons as these are the only ones that work correctly with TTS. Only use icons if they are used on the BGS, i.e. do not use the icon to replace a spelled out destination such as “Toronto Pearson International Airport” or “Powell River Ferry”. Note that these icons do not work using French TTS.
- For more general information on BGS segment naming, please refer to the USA Wazeopedia sections for wayfinders and entry/exit ramps.
Please follow the Canada Post street type abbreviation at all times even if it differs from in-real-life road signs.
See https://www.canadapost.ca/tools/pg/manual/PGaddress-e.asp#1437339 for full details in English and French.
Check to make sure that the Canada Post Abbreviation has a working TTS. If it does not, then please check the list of abbreviations below. Note that while Canada Post does not abbreviate "Place" in French, Waze does abbreviate it as "Pl", just like Canada Post does in English.
With regards to the use of ordinals, please avoid using them unless they are consistently on most street signs. "109 St" is preferred to "109th St," generally.
Additionally, please do not shorten names when they are integral to understanding the street name:
e.g. Bad: N St, S St, Ave Rd e.g. Good: North St, South St, Avenue Rd
It is recommended to use the Custom Canadian WME Validator Script. It will highlight all the incorrectly abbreviated street names.
Street Name Abbreviations
|Approved Abbreviation||Pronunciation||Do Not Use|
|Av||Avenue (French)||Avenue, Ave|
|Ave||Avenue (English)||Avenue, Av|
|Boul||Boulevard (French)||Boulevard, Blvd|
|Harbr||Harbour||Harbour, Harbor, Hbr|
|Terr||Terrace||Terrace, Ter, Tce|
|Tsse||Terrasse (French)||Terrasse, Terr|
The USA has a standardized Functional Classification system which has been adopted by Waze Champs as the method for classifying different road types. Overall, this has resulted in use of the highway types for arterial roads in the metropolitan areas, with the Primary Street type being available for collector-type roads.
Unfortunately, Canada does not have the same standardized government-published maps to adopt here, but we can consider many of the same principles. This was first looked at in Edmonton, and seems to have been met with great success. With that in mind, we'd like to consider the following criteria for use within metropolitan areas and any city with a population exceeding ~40,000. In the event that the infrastructure of a smaller city has been designed with arterial routes, this may be adopted there, but will typically be less obvious.
Most local governments publish road classification maps, although there is little standardization between them so each municipality must be treated separately. Lists of existing conversions to Waze road types may be found on the province-specific wiki pages:
- British Columbia
- New Brunswick
- Nova Scotia
- Prince Edward Island
- Newfoundland and Labrador
Road type: Freeway
Primary name: Hwy ## (e.g. Hwy 1)
Alternate: Trans-Canada Hwy
There are parts of the TCH that travel through National/Provincial parks with frequent stops, reduced speed and undivided portions. These segments should be reduced to a Major Highway with Freeway routing until the speed increases, stops are minimized or the highway is divided again.
Roads in cities
As a highway enters a city/town, it often becomes a named street, and sometimes would no longer fit the usual criteria for a "highway".
Due to a number of reasons, including long-distance routing issues, as well as appearance, the highway should remain as the same type it entered the city/town (except if it's a Freeway -- if it no longer fits the Freeway criteria, it may be downgraded to Major Highway with Freeway routing until it is again a Freeway).
The road type designation should follow the entire numbered route.
In general, Freeways will have:
- Multi-Lane, divided road
- No cross traffic
- No stop lights (except for ramp meters)
- No stop signs
- No parking
- No stopping (except for toll booths, freeway access metering, movable bridges, and traffic congestion)
- Highest speed limits (relative to region)
- Some have minimum speed limits
- Limited access:
- Access restrictions vary by region but some typical restrictions are:
- No pedestrians
- No bicycles
- No mopeds
- No Animal-Drawn Vehicles
- Entrance ramps are typically designed with an acceleration zone so that cars can accelerate up to freeway speeds before merging into freeway traffic
- Exit ramps are typically designed with a deceleration zone so that traffic can exit the freeway at freeway speeds without obstructing traffic, then have sufficient distance to slow down before any turns
- Access restrictions vary by region but some typical restrictions are:
When considering the road type, use the above noted Freeway classification as a guideline, with the idea that a Canadian "Freeway" may lack one of the criteria (e.g. Whitemud Freeway in Edmonton is 80 km/h, but meets all other criteria; Hwy 16 W of Edmonton doesn't have ramps for every junction, but meets all other criteria)
Use for major arterial roads. Often these have 2-3 lanes (or more) in each direction, and may be structured to be turned into freeways eventually. Usually this means relatively few intersections, higher speed limit, and higher capacity.
Additionally, if a road enters an area as a Freeway, but then loses its limited-access situation, it will generally continue on as a Major Highway.
If only one type of arterial is used by the municipality on their maps, the decision between a "major" and a "minor" will be that of relative importance and capacity. Generally, a "major" will have 2+ lanes, whereas a minor may only have one. Local knowledge is also especially useful in determining this.
Use for arterial roads. They are more direct than using collector roads and sometimes have slightly increased speed limits.
Suitable for collector roads through neighbourhoods and thoroughfares that aren't arterial.
Alleys and Laneways
Alleys and laneways should never be added to the map without approval from a Canadian Champ. In some cases (e.g. Toronto area), we have left the ones in place, but in most cases they should be removed.
This is particularly relevant to basemapped areas that included them -- e.g. Saskatchewan -- small towns should certainly have the alleyways removed.
In places where they are retained, they should have their city name set and the "None" box checked for Street Name. They should also be changed to Parking Lot street type. Do not use the Narrow Street type.
In considering whether one should be mapped, the primary question is "would it be appropriate for a stranger (e.g. pizza delivery guy) to park there and enter the residence from that side" - if the answer is "no", then they should definitely not be mapped.
Parking Lot Roads
Please read the Best Map Editing guidelines on parking lot roads. As of October 2018, North America has new guidelines: all parking aisles are to be mapped. US champs recommend enabling U-turns at the end of aisles, but this should not be done in Canada.
Canada has active "Traffic Locks", these locks are based on usage from users. They are limited to a max rank of 4, but can be any rank below.
Segments that have restricted turns must be locked to a minimum Level 3.
If the current lock or traffic lock is higher than the minimum standards listed below, please don't lower the lock.
|Segment Type||Minimum locks|
|highest rank of connected segment|
PUR should be reviewed for accuracy, once approved all relevant information pertaining to the place should be entered. Please use each company's website to gather all the information you can. Once a place is complete please lock to rank 3.
This practice will prevent app trusted users and most IGN editors from making incorrect changes to places we know are right. App trusted users and IGN editors are rarely rank 3.
Following are general standards for place locking in Canada:
|Place Type||Minimum locks|
|Major Tourist Attractions/Landmarks||4|
Telephone Number Format for Waze Places
This number format allows mobile phones, regardless of their home network, to dial a number without having to modify the number first.
Place Naming in Canada should adhere to the following guidelines. Following the government agency naming guide is a list of businesses which are chains or franchises. Please use these name spellings when creating or updating a place.
Hospitals & Other Medical Services
Hospitals with Emergency Rooms are the only place type permitted to use the Hospital category. All other day clinics, surgical centres, doctors etc must use the Doctor / Clinic category. Other non core medical services services such as Naturopaths, physio-therapists, chiroprators, etc should use the Office category. Emergency Rooms must have a separate Waze Point Place with "ER/Urgence" prefixed in the primary name, for example:
- ER - Brampton Civic Hospital
- ER - St. Michael's Hospital
- Urgence - Hôpital de Verdun
Police Stations: City, Agency followed by division name, for example:
- Toronto Police 12 Division
- Peel Police 22 Division
- OPP Collingwood Detachment
Fire Stations: City, Agency followed by station number, for example:
- Brampton Fire Station 221
- Toronto Fire Station 347
If a secondary business within another business location has a different category, contact numbers and opening times, it may be added to the map as a new (second) point place with the new primary category and relevant contact details and opening times. Typical examples of this type of nesting would be pharmacies or post offices within supermarkets or superstores.
Place Name Harmonization
If you don't find the business you're looking for, please use this form to submit the missing information.
A script is available to assist with Place Harmonization and has been localized for use in Canada.
For modification of fuel retailers in Canada, please use the Gas Stations Brands form.
When to use Area or Point in Canada
Here is the Canadian guidance on selecting Area or Point for Places in the Waze Map Editor.
Optional Area shall only be used after consulting local area managers on regional guidelines. The place must be a significant landmark with navigational value in the community. For example: a Tim Hortons in Hepburn, SK (population 500) is of significance. However, the same sized Tim Hortons is of zero significance in the Greater Toronto Area.
We do not want to impose hard & fast rules for the Optional Area category. Please use some judgement, we do not want to see wall-to-wall areas for every single building structure on the map.
Optional Area shall be landmarked to just the building structure only, do not include the parking lot area.
Fence-line Areas shall be landmarked from fence line to fence line to include all parking lots, roads, and anything associated with the property. Parking lot roads (PLRs), parking lots, and gas stations all serve the same purpose.The Primary Category for a Place is used to determine whether to use a Point or Area.

If the feature is too small to map conveniently with an Area Place, it should not be mapped at all.|
Please refer to the USA Speed Limit guidelines.
Temporary Construction Speed Limits
Do not change the speed limit due to temporary construction; exceptionː a local editor who takes the route on a daily commute and assumes full responsibility of updating the speed limit.
Ramp Speed Limits
For ramps with only advisory speed limit signs, use the highest speed limit of the in or out segment.
- Recommended not to map them in Canada.
- If the ferry has a toll, mark it as a toll road.
Where appropriate, reply to users with the standard replies provided by the URC-E script. If 7 days pass without a reply from the user, send the reminder message. Close the UR if a further 7 days pass without a reply from the user.
