Footnotes ...

<1>The elevation is an estimate for the area around Newmarket - it will be higher in some places and lower in others.
<2>Of the area codes for Newmarket, area code (289, 365) is an overlay.
<3>The Canadian Postal Code consists of 6 characters, where the first three characters are the 'Forward Sortation Area (FSA)', with the last three characters being the 'Local Delivery Unit (LDU)'. In the case of Newmarket, we provide only the FSA and not the LDU. The Canadian Postal Codes were created as a way of grouping addresses to make delivery more efficient. So keep in mind that any given Postal Code is only 'loosely' associated with a community (such as Newmarket). The boundaries of the Postal Code can be changed, re-assigned, eliminated or overlapped with other Postal Codes. When looking for a Postal Code, whether Newmarket or elsewhere, it's always best to check the website of the Canada Post / Postes Canada.
<4>While we're fans and frequent users of TripAdvisor, you should know that we're also members of the TripAdvisor affiliate program.
<5>If we found a location and have questions about the accuracy of our information, we will simply say that the marker is 'in the vicinity'. We are not confident about the location and the position of our marker is only a rough guide. If we have too many doubts about the location, we will not include it in our database.
