Here are my two cents worth:
When COVID hit, things shut down and everyone in North America was forced to lock down. Many people ended up saving some money that was originally destined on discretionary spending. Governments helped that by giving out billions through government programs such as CERB. When things opened up the consumer spent all that saved money on housing, furniture, cars and other durable goods-things that move by truck. This purchase power that was available gave us the big boost of Q1-2022.
Now that money has been all spent-the hangover starts. Governments printed money spurs Inflation which drives up all costs, interest rates jump, insurance rates on new cars balloon, CERB is getting clawed back, CPP and EI rates deducted on your paycheque have increased, CARBON TAX eats away at your pocketbook and to top it all off the HST on everything just robs you at every turn. The consumer now is stuck with spending on immediate non-durable items - interest, insurance, utility bills, gasoline, taxes, more taxes etc.
In other words, nobody is spending money on the things that get loaded on trucks. The new housing market is stagnant, automotive is slow along with other markets that drive the trucking industry are hitting some troubles. We will not see much turn around until both spending changes and truck capacity decreases.
I'm banking on Q3-2024 Hold on to your hats!
