Insulator Cheque

Employers

Employer to change

Name

Each employer has its own rate, rules and TD1. A new employer starts CPP, EI and tax from zero, even if you maxed out at the last one.

Log your hours day by day and see every cheque: straight time, time and a half, double time, vacation and holiday pay, dues, CPP, EI, an income-tax estimate and living-out allowance. The year view adds it all up. Pick your province and agreement on the Settings tab: Alberta Local 110 (all five segments of the CLR-A agreement and the NMA and GPMA maintenance agreements), BC and Yukon Local 118 (the BCICJV agreement and the CLR standard agreement), Saskatchewan Local 119, Manitoba Local 99, Ontario Local 95 (three ICI zones and three maintenance schedules), Quebec calorifugeurs under the CCQ sector agreements, and Nova Scotia Local 116 (mainland and Cape Breton) are built in, with each province's payroll tax. The week shown first is an example; change any box.

These come from the TD1 forms you filled in for this employer. Most people claim the basic amounts. Your pay stub may list them as "TD1 claim" or "claim code".

Pension hours

For the employer picked above, copy these from the year-to-date column of its last pay stub before you started logging. Pension hours are on your plan statement or portal; they make the Year tab's pension totals and its 350-hour check right. They make the CPP and EI stop point and the year totals right. Leave them at 0 if you log from January.

How it's worked out

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 (Local 131 posts its agreement to members only), Newfoundland and Labrador (Local 137's agreement is a scan whose later steps are not printed) and Prince Edward Island (no public insulators' agreement); travel time and mileage, call-outs and show-up pay, daily travel-expense zones (type the week's total in the travel box), Alberta's 12-hour turnaround shift paid as a flat 12 h, the temporary-foreign-worker and pensioner pension-as-wages schedules, probationary, provisional, asbestos-removal and firestop-improver rates outside Alberta (use Custom rate), Quebec's isolated-site (Annexe B-1) rates, the Saskatchewan, Manitoba and Nova Scotia maintenance agreements, the $0.75 Better SuperVision premium, the $2.00 an hour Alberta journeyperson RRSP deduction and 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 (CLR Alberta, CLR-BC, CLRS, the Ontario employer bargaining agencies, the ACQ, NSCLRA, CLRA NL 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.

Privacy

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, and which poster, QR code or link brought you here. It can't identify you.
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 you had selected, and your phone's browser type.

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.
