If you're preparing for IELTS as part of a Canadian immigration or study application, you've probably already noticed that "IELTS prep resources" is an enormous and uneven category, some are official, some are free, some are excellent but cost money, and a fair number are neither useful nor honest about what they offer. This post is a grounded look at where to actually practice, with a specific, defensible reason for including each one. It won't cover the score requirements themselves, for that, see our separate guide to IELTS for Canada, this is purely about where to prepare.
1. British Council
The British Council is one of the two organisations that actually administer the IELTS test in Canada, which makes their own practice materials worth using for a specific reason: format familiarity. Their free sample tests and preparation guides are built by the same body that writes the real exam, so the question types, instructions, and answer sheet layout match test day exactly. That sounds like a small thing until you're sitting the real test and realise you've never actually seen the instructions worded that way before, or practiced clicking through a computer-delivered interface identical to the one you'll use on the day. If you only do one thing to get comfortable with the test's actual format and instructions before sitting it, working through the British Council's official materials is a sensible place to start.
2. IDP IELTS
IDP is the other official test provider, and in many Canadian cities it's the more common option for booking your actual test date. It's the same test, scored to the same standard, regardless of which of the two you register with, the differences are mostly logistical (test centre locations, available dates, and each organisation's own practice tools and booking system). If you're deciding between the two for registration, it comes down to availability and convenience in your city rather than any difference in the exam itself; our other comparison guides go into more format-level detail if that's what you're after.
3. Cambridge IELTS Official Practice Books
Cambridge University Press publishes the closest thing IELTS has to a "past papers" series, the Cambridge IELTS books are compiled from genuine retired test material, which is why they're widely considered the gold standard for realistic practice questions. Because the passages, prompts, and audio all come from tests that were actually administered, the difficulty and phrasing feel authentic in a way that's hard for any third-party material to fully replicate. The honest caveat is that these aren't free: each book is a paid purchase, and you'll typically want several volumes to get enough practice volume, which adds up if you're working through more than one or two. If your budget allows for it, they're worth owning as a supplement; if it doesn't, that's exactly the gap free, full-length resources need to fill.
4. PrepTest Hub
This is our own site, so we'll be specific rather than promotional: PrepTest Hub offers free, full-length, properly timed mock tests across all four modules, Listening, Reading, Writing, and Speaking, with instant scoring and per-question explanations, and no registration or paywall standing between you and a practice test. We won't claim to be the "best overall" IELTS resource, because that's not a claim anyone can back up honestly. What we can say, specifically, is that among free options, full-length timed tests with real band-style scoring and explanations for every question are harder to find than you'd expect, most free tools give you either isolated practice questions or an essay checker, not a complete, scored simulation of the exam. If that's what you need, an honest, timed baseline you can retake as your prep progresses, that's what this site is built for. Start with a practice test to see where you currently stand.
5. CELPIP
It's worth knowing that IELTS isn't the only English test IRCC accepts for Express Entry and most other Canadian immigration streams, the Canadian English Language Proficiency Index Program (CELPIP) is the other major option, and it's specifically designed around Canadian English and Canadian contexts. The practical difference that matters most: CELPIP is recognised only in Canada and the United States, while IELTS is accepted far more broadly worldwide, including by universities and immigration authorities outside North America. If Canada is your only destination and you'd prefer a test built around Canadian spelling, vocabulary, and scenarios, CELPIP is a legitimate alternative worth researching. If you might use your score for study or migration elsewhere too, IELTS's global recognition makes it the safer single choice.
6. IELTS Liz
IELTS Liz is a long-running, independent blog run by a former IELTS examiner, and it's a genuinely useful free resource for written explanations of Writing and Speaking criteria in plain language, the kind of detail that's easy to skim past in official guides. Posts that break down exactly what separates a Band 6 answer from a Band 7 one, sentence by sentence, are hard to find elsewhere for free, and that level of granularity is where the site earns its long-standing reputation. It's not a testing platform and won't give you a timed, scored mock exam, but as a reference for understanding what examiners are actually looking for, criterion by criterion, it's held up well over the years and is worth bookmarking alongside a proper practice-test resource.
Putting It Together
None of these resources fully replaces the others, official practice material teaches you the format, Cambridge books give you the most authentic questions if you're willing to pay, independent blogs like IELTS Liz explain the marking criteria in accessible language, and a full-length scored mock test tells you where you currently stand. Use them together rather than picking just one. When you're ready to see your current band-level performance under real timed conditions, our free practice tests are a good place to start, and if you specifically need the Canadian score requirements for your visa or immigration pathway, our IELTS for Canada guide covers that in detail.
