Cheque Calculator & Hours Log

Everything below is for the employer picked on the Settings tab. Rates step on the agreement's own dates and the calculator uses the column in force for the week you're looking at. Hours are your hours on site, breaks included, the way the agreement's overtime rules count them.

• Filling in as foreperson: set that day's role under the date. Each day's hours are paid at that day's rate; overtime follows the same day rules.
• Holidays are built in for your agreement and moved to the day they're observed. Untick Stat to switch one off, or tick it for a day your job observes instead.
• CPP and EI (2026): CPP 5.95% after a $67.31 weekly exemption until $4,230.45 for the year, then the second CPP at 4% on earnings between $74,600 and $85,000. EI 1.63% until $1,123.07. Quebec: QPP 6.3% to $4,479.30, EI 1.30% to $895.70, QPIP 0.43% to $442.90. The log counts these up week by week, separately for each employer.
• Income tax uses the 2026 federal and provincial payroll formulas (CRA T4127, July 2026 edition) the way payroll does: the week's pay times 52, union dues taken off first, with each province's extras (BC tax reduction, Ontario surtax and health premium, Quebec abatement). Real cheques usually land within a few dollars. Quebec provincial tax is an approximation of the Revenu Québec formula.
• Living-out allowance and travel are reimbursements. They're normally tax-free when you file a TD4 with your employer, and they don't get vacation or holiday pay. Tick "This employer pays living-out" on the Settings tab and new days you log will have LOA on.

Not included: New Brunswick and Prince Edward Island (we could not get a readable copy of their insulators' agreements), Newfoundland and Labrador (Local 137's agreement is a scan whose later steps are not printed); travel time, mileage and daily travel-expense zones as their own lines (type the week's travel money in the travel box, which is counted as tax-free), call-outs and show-up pay, Alberta's 12-hour turnaround shift paid as a flat 12 h, the temporary-foreign-worker and pensioner pension-as-wages schedules, probationary, provisional and asbestos-removal rates, firestop-improver rates outside Alberta and Saskatchewan commercial work (use Custom rate), Quebec's isolated-site (Annexe B-1) rates, the Saskatchewan, Manitoba and Nova Scotia maintenance agreements, the Alberta Better SuperVision premium ($0.75 an hour on Segments A to C, $0.50 on D and E), the Mortuary Plan assessment, and union dues a Local does not publish (enter them from your stub). Rules the calculator can only approximate are named in each agreement's notes. Employer health, pension and training contributions aren't on your cheque; the pension part is shown as a memo line under the cheque and on the Year tab.

Made by a union worker, for union workers. Independent tool. Not made by or affiliated with the International Association of Heat and Frost Insulators and Allied Workers, any of their locals or councils, any employer bargaining association or contractor group (CLR Alberta, CLR-BC, the BC Insulation Contractors Joint Venture, CLRS, CLRAM, the Master Insulators' Association of Ontario, the ACQ, NSCLRA and others), the CCQ, the National Maintenance Council or any contractor. This is an estimate, not payroll advice. Your stub and your steward have the final word.

Your hours, pay, employers and settings stay on this phone. There's no account and no sign-in, and we never see your log.

What we do receive:

• When you open the app: an anonymous count. It includes a random number your phone makes up, the phone type, your province, which poster, QR code, key card or link brought you here (for a key card, the last six characters of its key; for a friend's share link, their share code), whether it was opened inside Facebook's or Instagram's browser, and whether the page was on screen. It doesn't include your name or email.
• When you pass the app on: the Share and Copy link buttons and the QR code under Get it on your phone carry a share code your phone made up at random. It lets us count how many people arrive by your link and install the app. It's a different number from the usage count above, and your own phone never sends it to us. We only see it when someone opens your link, and it doesn't tell us who you are.
• If you buy a key: your email, passed to us by Stripe and kept with your key so we can find it if you lose it. Stripe handles your card, and we never see the number.
• When you turn on a key: your phone's random number, so one key works on up to three phones.
• If you use the feedback box: your message, your email if you give it, the agreement, job class and province you had selected, your phone's browser type, and the same random number as the usage count.

We don't sell or share any of it, and there are no ads or tracking scripts. The site is hosted by Cloudflare and payments go through Stripe. They see what any web host or card processor sees.

To see or delete what we hold about you, send a note through the feedback box with your key or email.
