Maple’s share of its area codes

Within area code 289, Maple accounts for only 11 of 772 prefixes (1.4%): the code is dominated by Hamilton and spread over 87 rate centres. Within area code 365, Maple accounts for only 9 of 706 prefixes (1.3%): the code is dominated by Markham and spread over 88 rate centres. Within area code 905, Maple accounts for only 6 of 773 prefixes (0.8%): the code is dominated by Hamilton and spread over 94 rate centres. Within area code 742, Maple accounts for only 2 of 148 prefixes (1.4%): the code is dominated by Brampton and spread over 68 rate centres.

Who holds these numbers

Rogers Communications Canada Inc. (Cable) holds the largest share at 6 prefixes, 21.4% of the total, ahead of 13 other carriers. Code by code: in 289, Rogers Communications Canada Inc. (Cable) leads with 2 of 11 prefixes ahead of 7 others; in 365, Iristel Inc. leads with 2 of 9 prefixes ahead of 7 others; in 905, Rogers Communications Canada Inc. (Cable) leads with 3 of 6 prefixes ahead of 1 others; in 742, Beanfield Technologies Inc. leads with 1 of 2 prefixes ahead of 1 others. No carrier holds prefixes in every one of Maple’s 4 area codes, while 10 appear in just one.

Wireless and wireline

None of Maple’s holders carries a mobility brand in its registered name: all 28 prefixes belong to wireline or wholesale carriers, among them Rogers Communications Canada Inc. (Cable), Bell Canada, Iristel Inc and Fibernetics Corporation. A call showing a Maple number therefore nominally comes from a landline, cable or VoIP platform rather than a locally assigned cellphone.

How the allocation was built up

Maple’s dated assignments run from 2000 to 2024. The busiest period was 2005–2009, when 8 prefixes went to 5 carriers. 3 prefixes (11%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. Since 2020 another 6 prefixes have been added, so the rate centre is still growing.

Maple’s oldest prefixes, the ones the register leaves undated, belong to Bell Canada and Rogers Communications Canada Inc. (Cable): these carriers made up the landscape before competition arrived. The first dated assignment went to Bell Canada in 2000. The most recent arrivals are FGLTEL Inc. (2022), Beanfield Technologies Inc. (2021) and TekSavvy Solutions Inc (2021), a sign that new carriers are still asking for numbers in Maple.

Maple has only 28 prefixes, or 280,000 numbers: a small rate centre, where the arrival of a single new carrier visibly changes the landscape.

No single carrier dominates Maple: the leader, Rogers Communications Canada Inc. (Cable), holds only 21.4% of the prefixes against 13 competitors, a sign of a highly fragmented market where cable companies, mobility brands and VoIP providers weigh as much as the incumbent.

Demand remains steady: 24.0% of the dated prefixes go back to the last ten years, the most active period being 2005–2009. The rate centre is growing at a regular rather than explosive pace.

Dialling a Maple number

Maple is served by 4 overlaid area codes (289, 365, 905 and 742). A 742 number is no more “out of town” than a 289 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Maple shares area codes 289, 365, 905 and 742 with at least 20 other rate centres, including Hamilton, Brampton, Oshawa, St. Catharines-Thorold, Oakville, Markham, Ajax-Pickering and Cooksville. The largest of them, Hamilton, holds 222 prefixes in 289, 365, 742 and 905; the smallest on the list, Dunnville, has just 28.

What a Maple number tells you

A number attached to Maple tells you that its prefix was issued to a carrier for this rate centre in Ontario, most often Rogers Communications Canada Inc. (Cable). It does not tell you where the handset is today: a subscriber may have ported the number to any of the 14 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and an Ontario area code is easy to borrow to look local.

Reading a register entry for Maple: code 289-342 is recorded for Rogers Communications Canada Inc. (Cable), so every 289-342-XXXX number (10,000 possible) descends from that assignment. “Maple, Ontario” there names a rate centre, not a municipality, and several area codes overlay it.

Had a call from a Maple number?

No clear pattern in reports on these numbers yet. If a call worried you:

1. Call back on a number you trust

   If a caller says they are your bank, the Canada Revenue Agency, a courier or your phone company, hang up and call the organization on the number from its website or your statement, never the number that called you. Caller ID can be faked.

2. Report the fraud

   Report the call or text to the Canadian Anti-Fraud Centre online or at 1-888-495-8501. If you lost money or gave out personal details, tell your bank first, then your local police.

3. Register on the National Do Not Call List

   Registering a landline or mobile on the National DNCL is free. Registered charities, political parties, newspapers and companies you already do business with may still call.

4. Forward suspicious texts to 7726

   Forward a scam or spam text to 7726 (SPAM on the keypad). It's free, and your carrier uses it to block the sender. Don't tap links or reply.
