Canada gave the world insulin, basketball, and standardised time. It can also give you something else:
a perfect lens for mastering one of English grammar’s trickiest contrasts — because Canadian history
is full of completed past moments sitting right beside their ongoing present relevance.
That tension is exactly what the past simple and present perfect are built to express.
If you are starting from scratch with these tenses, try our B1 guide to the present perfect and past simple first. This B2 lesson goes further: we look at the subtle cases, boundary conditions, and common higher-level errors that trip up even advanced learners — and especially Spanish speakers.
The Core Principle (B2 Version)
Present perfect = a past action whose results, relevance, or connection to now still matter to the speaker.
The key is not how long ago something happened — it is whether you frame it as finished and closed (past simple) or connected to the present (present perfect).
At B2, the most reliable guide is still the time expression:
🔵 Past Simple Signals
- yesterday, last week / month / year
- in + year: in 1921, in the 1980s
- … ago: three years ago, long ago
- when: “when I was a student”
- at that time, once, then, at + time
🟢 Present Perfect Signals
- since + point: since 1969, since Tuesday
- for + duration: for decades, for years
- already, yet, just, still (not yet)
- ever, never (life experience)
- this year / this month / today / recently
Formation Reminder
| Form | Structure | Canadian Example |
|---|---|---|
| Past Simple (+) | Subject + V₂ |
Banting discovered insulin in 1921. |
| Past Simple (−) | Subject + did not + V₁ |
Canada did not join the United States. |
| Past Simple (?) | Did + subject + V₁ ? |
Did Naismith invent basketball? |
| Present Perfect (+) | Subject + have / has + V₃ |
Canada has recognised Palestine since 2025. |
| Present Perfect (−) | Subject + haven't / hasn't + V₃ |
I haven’t visited British Columbia yet. |
| Present Perfect (?) | Have / Has + subject + V₃ ? |
Have you ever tried poutine? |
🍁 Canadian History Through the Lens of Tense
Canada is an ideal country for this grammar lesson because its story constantly shifts between fixed historical moments and their living, present-day impact. Let us look at five real stories and notice how tense choice changes the meaning.
1. The Discovery of Insulin — Past Simple (Specific Moment)
In 1921, Dr Frederick Banting and medical student Charles Best isolated insulin at the University of Toronto — one of the defining medical breakthroughs of the twentieth century. The Nobel Committee awarded Banting and his supervisor John Macleod the Nobel Prize in Physiology or Medicine in 1923.
We use the past simple throughout because these are completed events at specific past dates: in 1921, in 1923. The discovery is over; it belongs to the past. Compare:
“Insulin has saved millions of lives since its discovery.” — present perfect with since, because the life-saving impact continues right now.
2. Official Bilingualism — Present Perfect + “since” vs Past Simple
Canada has been officially bilingual since 1969, when the Official Languages Act recognised English and French as equal at the federal level. The act was passed in 1969 (past simple — a specific completed event) but the bilingual status has continued ever since — which is why we describe the current situation with the present perfect today.
This is a classic B2 test point: the moment something started is past simple; the ongoing state it created is present perfect + since.
3. Indigenous Languages — Present Perfect + “for”
The Cree language has been spoken across Canada for thousands of years. Today it counts approximately 84,000 speakers, making it the most widely spoken Indigenous language in the country. By contrast, European settlers arrived in the early seventeenth century — a completed historical event, past simple.
Duration from a past point to now → present perfect + for. A closed historical action → past simple.
4. Standard Time — A Canadian Invention (Past Simple)
Sir Sandford Fleming, a Canadian engineer, proposed the worldwide system of standardised time zones in 1879. North American railways adopted his system in 1883. Specific year → past simple. The modern perspective: “Fleming’s work has shaped how the entire world organises its day” — present perfect, because the impact is still with us.
5. The Territory of Nunavut — Contrasting Both Tenses
Nunavut became Canada’s newest territory on 1 April 1999 (specific date → past simple). Since then, Nunavut has become a symbol of Indigenous self-determination, and the territory has attracted global attention for its unique culture and Arctic landscapes. The event is past; the significance is ongoing.
The B2 Nuances You Must Know
A. Unfinished Time Periods
When the time period containing the action is not yet finished, British English uses the present perfect. This is one of the clearest differences from American English:
American English: “Canada was in the news a lot this year.” (also acceptable in AmE, but avoid in B2 exams)
Unfinished time periods: today, this morning, this week, this month, this year, this century, this decade.
B. “Just”, “Already” and “Yet”
These three adverbs almost always trigger the present perfect in British English. Just = “a very short time ago”; already = “sooner than expected”; yet = “up to now” (questions and negatives).
“I have already tried poutine twice on this trip.” — sooner than expected
“Have you yet visited Nunavut?” — formal question
“The report hasn’t been published yet.” — negative
C. Announcement Then Detail
When you introduce news for the first time, use the present perfect. Once you add specific details, switch to the past simple:
“The team found the creature last Tuesday near Banff.” (detail + specific time — past simple)
D. “For” vs “Since” — Getting Both Right
| Word | Meaning | Canadian Example |
|---|---|---|
| for | Length of time (duration) | Canada has been a federation for over 150 years. |
| since | Starting point in time | Canada has been officially bilingual since 1969. |
⚠️ Common Mistakes for Spanish Speakers
❌ “I have arrived yesterday.”
✅ “I arrived yesterday.”
In Castilian Spanish, ayer can combine with the pretérito perfecto compuesto (“ayer he llegado”). In English, yesterday is a specific past time marker and always forces the past simple — no exceptions.
❌ “I know him since five years.”
✅ “I have known him for five years.”
Spanish uses the present simple with desde hace for ongoing states (“Lo conozco desde hace cinco años”). English requires the present perfect + for (duration) when a state began in the past and continues now.
❌ “Banting has received the Nobel Prize in 1923.”
✅ “Banting received the Nobel Prize in 1923.”
A specific year in the past always requires the past simple. The year makes the action feel closed and finished — present perfect is not possible here.
❌ “When did he discover it? — He has discovered it in 1921.”
✅ “When did he discover it? — He discovered it in 1921.”
After a when question about the past, always answer with the past simple. When asks for a specific time, and a specific time means the past simple.
❌ “I am living in Canada since 2020.”
✅ “I have been living in Canada since 2020.”
The Spanish construction hace + duration + que + present simple (“Hace seis años que vivo aquí”) maps to the English present perfect (simple or continuous) — not to the present simple or continuous.

Quick Practice Quiz
a) has become b) became c) becomes
a) never ate b) have never eaten c) didn’t never eat

▶ Show Answer Key
- b) became — “in 1867” is a specific past year → past simple.
- b) have never eaten — “never” signals a life experience without a specific time → present perfect.
- b) has been spoken / for — ongoing state from past to now → present perfect; “thousands of years” is a duration → for.
- b) did…propose / proposed — “when” question → past simple; specific year in the answer → past simple again.
- a) have announced / found — announcement = present perfect; “last Tuesday” = specific past time → past simple.
